On the basis of structural similarity between the m- and rRNA binding sites which underlies the molecular mechanism of the autogenous control of expression of the rplJL genes, mediated in prokaryotic organisms by ribosomal protein L10, we attempted to find the potential mRNA target sites in S. griseus and S. coelicolor. The potential targets found in both species of Streptomyces are of highly conserved structure and contain elements similar with the L10 binding domain of the 23S RNA. Compared to the L10, mRNA targets of Enterobacteria, Thermotoga maritima and Synechocystis, the target sites of Streptomyces contain a larger number of conserved and specific structural elements, similar in both analyzed species. Comparison of the structural organization of the "Streptomyces" and "Enterobacterial" types of the L10 mRNA targets with the structure of the L10 binding domain in the 23S RNA reveals that the elements, conserved in all the mentioned targets, are located in the ssA and dsA regions. The structure of the potential L10 mRNA target sites, which mimic the rRNA target of the regulatory ribosomal protein L10, gives evidence for the autogenous L1-0mediated control of expression of the rplJL genes in Streptomyces.

fulltext УДК 577.21 Eugenia В. Paton THE POTENTIAL mRNA TARGET SITES FOR THE RIBOSOMAL PROTEIN LIO FOUND IN STREPTOMYCES GRISEUS AND S. COELICOLOR GIVE EVIDENCE FOR THE AUTOGENOUS REGULATION OF EXPRESSION OF THE rplJL GENES On the basis of structural similarity between the m- and rRNA binding sites which under* lies the molecular mechanism of the autogenous control of expression of the rplJL genes, mediated in prokaryotic organisms by ribosomal protein LIO, we attempted to find the potential mRNA target sites in S. griseus and S. coelicolor. The potential targets found in both species of Streptomyces are of highly conserved structure and contain elements similar with the LIO binding domain of the 23S RNA. Compared to the LIO, mRNA targets of Enterobacteria, Thermotoga maritima and Synechocystis, the target sites of Streptomyces contain a larger number of conserved and specific stru­ ctural elements, similar in both analyzed species. Comparison of the structural organi­ zation of the «Streptomyces» and «Enterobacterial» types of the LIO mRNA targets with the structure of the LIO binding domain in the 23S RNA reveals that the elements, conserved in all the mentioned targets, are located in the ssA and dsA regions. The structure of the potential LIO mRNA target sites, which mimic the rRNA target of the regulatory ribosomal protein LIO, gives evidence for the autogenous LlO-mediated control of expression of the rplJL genes in Streptomyces. The expression of genes in the majority of ribosomal protein operons in prokaryotic organisms is regulated autogenously at the translational le­ vel [1]. This mode control is achieved due to the possibility of the re­ gulatory ribosomal proteins, encoded by the mRNA of the controlled ope­ rons, to bind in a competitive manner the target sites in the m- and rRNA. The structural organization of these sites is highly homologous. In case of the rplJL operon, whose genes are regulated by r-protein LIO (or its 1 :4 complex with L12) [2] we observed the possibility for heterologous translational feedback control in Enterobacteria [3, 4], provided by the highly conserved structure of both, the regulatory LIO proteins [5] and their mRNA target sites [6]. Of particular interest is the fact, that in case of the LIO target sites, whose structure is proved for Enterobacteria [6] and putative — for Synechocystis PCC 6803 [7] and Thermotoga ma­ ritima ([8]; Paton and Zhyvoloup, unpublished data), the degree of ho­ mology between the mRNA target sites is higher than between the res­ pective rRNA targets. Moreover, additional structural similarity between the m- and rRNA targets of the LIO protein is characteristic of Entero­ bacteria, Synechocystis and Thermotoga. This makes it reasonable to as­ sume that the L10-RNA interaction, which mediates the autogenous re­ gulation of the rplJL genes expression is species- and organism-specific. Existence of the «specifying» complementary structural elements, is to be found in both, the regulatory proteins [9] and their mRNA binding sites [6—8]. The latter might be of importance to provide the efficient recognition and tight binding the LIO protein to the mRNA, which in the case of the rRNA target would be achieved via the cooperative binding of the neighbouring r-proteins. Comparison of the LIO binding regions in the rplJ leaders of seven enterobacterial species [6] reveals that the AA1571 — 1572 (ennumeration as in E. coli [10, 11]), whose interaction with the LIO protein had been proven by chemical analysis [11], are con- © Eugenia B. Paton, 1996 40 ISSN 0233-7657. БИОПОЛИМЕРЫ И КЛЕТКА. 1995. Т. 11. № I served. The conservation of AA1571—1572 in the potential LIO mRNA targets of Synechocystis and Thermotoga (see Fig.) allows an assump­ tion that AA1571—1572 in all o<f these mRNA targets, are involved in binding to a complementary conserved structural elements of the regu­ latory protein LIO. It is notable that the structural homologs of AA1571 — 1572 in the 23S rRNA belong to binding domain of r-protein LI I [12]. We reasoned that in other prokaryotic organisms whose rplJL genes were feedback-regulated by LIO, the regulatory ZJ#-mRNA interaction might also involve additional structural elements, however, possibly different from AA1571—1572. The present paper is devoted to the analysis of the rpU leader region of 5. griseus and S. coelicolor, whose nucleotide sequ­ ence was recently determined [13, 14]. The special attempt was made to find the potential LIO binding sites and, if it were the case, to compare their structural organization in the both species to the structure of the so far determined mRNA targets of LIO. The following logic underlied the search for the potential LIO mRNA target sites. The mRNA target site of the regulatory protein LIO is to be homo­ logous to the rRNA target in as much as to provide the competitive bin­ ding of the LIO protein. In all the cases documented so far [2, 6—8, 11] the mRNA target sites for the LIO protein are located in the untranslated rpU leader region. In both species of Streptomyces, the untranslated lea­ der precedes the start of the LIO cistron. We further analysed the struc­ tural homology of the rpU leaders of Streptomyces with the LIO mRNA target sites of Enterobacteria, Synechocystis PCC 6803 and Thermotoga maritima, as well as with the LIO binding domain of the 23S RNA of Streptomyces ambofaciens (see Fig., A). The alignment of the nucleoti­ de sequences was made using the ALIGN program (PCGENE software package). The secondary structure prediction was carried out using the RNAFOLD program (PCGENE). Motives of primary structure identical to the Synechocystis and the Enterobacterial consensus LIO mRNA tar­ get sites were found in the rpU leaders of both species of Streptomyces. Further on, the secondary structure of the potential mRNA LIO binding sites was calculated (results shown in Figure). One can notice the pronounced similarity of structure of both S. gri­ seus and S. coelicolor putative LIO binding sites with the consensus LIO binding domain of the 23S RNA [12]. The most striking similarity with the 23.S RNA is accounted for by the common general organization, whe­ re of particular interest is the presence in the mRNA targets of Strepto­ myces of the two (dsB and dsD) double-stranded regions, rather than a single (dsB) region, which is typical for all of the so far known LIO mRNA binding sites. The structural organization of the potential LIO binding sites is highly similar in 5. griseus and S. coelicolor. The single- stranded region С (ssC) is different from the relevant region of the 23S RNA, as a well as from the other prokaryotic mRNA targets. The latter would contain the typical conserved UUAA motif (see Fig., B). It is no­ teworthy that the dsC regions are conserved in both types of mRNA tar­ gets «enterobacterial» and «Streptomyces» like. However identical within the two types of targets are only the two pairs, G-C and C-G in the dsC region. The highest degree of homology of the mRNA targets in S. grise­ us and 5. coelicolor is found in the dsC, ssA and sdA regions (see Fig., B). The structure in dsC region is completely conserved, except the in­ ternal loop, which in 5. griseus is formed of the U, U, while in S. coeli­ color— of U, C. The bulged nucleotides are typical structural elements for the protein-nucleic acid interaction. Therefore, we should not exclude the possible species-specifying role of the loop in the dsC region. The dsB, dsC and dsD regions in both pro- and eukaryotic 23S RNA belong to the Lll binding domain [12], which is interchangable for E. coli and yeasts [15]. As already noticed, the mRNA targets of Enterobacteria, Sy­ nechocystis and Thermotoga, although lacking the dsD region, do conta­ in the conserved UUAA motif in the dsC (Fig.). Therefore the structural similarity to the Lll binding domain of the 23S RNA is present in both ISSN Ю233-7657. БИОПОЛИМЕРЫ И КЛЕТКА.. 1995. Т.

Asterisks denote the variable nucleotides; 6 — secondary structure of the L10 mRNA target, consensus for Entervbacteria, Th. maritima and Synechocystis. Asterisks denote the variable nucleotides. The conserved base pairs are denoted by lines types of the mRNA L10 targets («Enterobacterial» and «Streptomyces»), In Streptomyces, however, this similarity is much higher due to the pre­ sence of the dsD region and therefore makes it tempting to assume that Lll protein, in addition to L10, might be involved in Streptomyces in the control of expression of the, rplJL genes. The functional role of Lll here might consist in co-regulation of expression of the rplA and the rplJL genes. The structural elements which comprise the most important simila­ rity between the two types of mRNA targets, the «Enterobacterial» and «Streptomyces» like, are to be found in regions ssA and dsA. The con­ served elements in the ssA region are: the AGA motif on the left side and the A, adjacent to the first C-G pair of the dsA region, on the right side of region ssA. The C-G pair is the most essential conservation in the dsA region. The formation — of this C-G pair provides the most com­ plete structural similarity between the m- and rRNA targets of Ы0 [16]. This feature is exploited in the models of the conformational switches of the rplJ leaders of E. coli [2] and the six other species of Enterobacterid [6], as well as those of Thermotoga maritima and Synechocystis (Paton, and Zhyvoloup, unpublished) to explain the molecular mechanism of the L/C-mediated feedback regulation. The conservation of the C-G pair (dsA), and the adjacent A (ssA) in the putative mRNA target sites of the L10 protein of Streptomyces proves the functional importance of these ele­ ments for L10 binding. The identical elements of the mRNA and rRNA targets (ssA region and the C-G pair of dsA) suggest a complementary structural conservation in the regulatory protein. We reason that the; -RNTLL- motif, which is the only one conserved among the 17 analyzed L10 protein sequences, is complementary to the conserved structural ele­ ments in dsA and ssA regions of the RNA target sites [9]. It may be noted in conclusion that the potential L10 mRNA target sites found in the two species of Streptomyces, S. griseus and S. coelico- lor, prove once again the principle of feedback regulation of r-protein synthesis in prokaryotic organisms being based on the structural simi­ larity of the m- and rRNA targets, competitive for binding of the regula­ tory proteins. Similarly to other prokaryotes, the mRNA target of LW is located in Streptomyces in the untranslated rplJ leader region more than a 100 nucleotides upstream the L10 start codon and therefore points to the important functional role of the rplJ leader. The conserved struc­ ture of the found potential Ы0 mRNA target is an evidence of its func­ tional role for the autogenous control of expression of the rplJL genes in Streptomyces. The structural specificity of the L10 mRNA targets fo­ und in Streptomyces might reflect the degree of phylogenetic remoteness. Given the peculiarities of the structural organization of the L10 target, as well as of the whole rplJ leader region (Paton and Zhyvoloup, in pre­ paration), one might expect some other specific features pertinent to the molecular mechanism of the L/0-mediated autogenous control of the rplJL genes expression in Streptomyces. 6.
