== Function ==
[https://www.uniprot.org/uniprot/RS1_MYCLE RS1_MYCLE] Binds mRNA; thus facilitating recognition of the initiation point. It is needed to translate mRNA with a short Shine-Dalgarno (SD) purine-rich sequence (By similarity).

== Publication Abstract from PubMed ==
Ribosomal protein S1 of Mycobacterium tuberculosis (MtRpsA) binds to ribosome and mRNA, and plays significant role in the regulation of translation initiation, conventional protein synthesis and transfer-messenger RNA (tmRNA) mediated trans-translation. It has been identified as the target of pyrazinoic acid (POA), a bactericidal moiety from hydrolysis of pyrazinamide, which is a mainstay of combination therapy for tuberculosis. POA prevented the interactions between the C-terminal S1 domain of MtRpsA (residues 280-368, MtRpsA(CTD)_S1) and tmRNA; so that POA can inhibit the trans-translation, which is a key component of multiple quality control pathways in bacteria. However, the details of molecular mechanism and dynamic characteristics for MtRpsA(CTD)_S1 interactions with POA, tmRNA or mRNA are still unclear. Here we present the (1)H, (15)N, (13)C resonance assignments of MtRpsA(CTD)_S1 as well as the secondary structure information based on backbone chemical shifts, which lay foundation for further solution structure determination, dynamic properties characterization and interactions investigation between MtRpsA(CTD)_S1 and tmRNA, RNA or POA.
