RNA

Catalyzed reaction/ biological activity

• hybridizes to [gene|B729EFC0BF0D75765C2D2B0B4F397E0AEE11F1E7|ytdI] and [gene|5900CAC1CE367F33B267673A7FC210A3A269B30E|sucD] mRNAs to inhibit their translation and to destabilize them [pubmed|25643072]
• binds the 5' end of the [gene|73356B73D6C89D6569CECCC7295AF85CC7A1E6E3|yflS] mRNA to prevent its degradation by [SW|rnjA|RNase J1] [pubmed|28436820]

  additional information

  • the [gene|search|roxS ]RNA is degraded by the joined activities of RNase Y (initial endonucleolytic cleavage) and RNase J1 (processive degradation) [pubmed|22383849]
  • the [gene|6AC80B5916EEA851E9A7AF586341C58B7E69D8E7|roxS]-[gene|search|ppnKB ]and [gene|6AC80B5916EEA851E9A7AF586341C58B7E69D8E7|roxS]-[gene|search|sucC ]RNA duplexes form a cleavage site for RNase III [pubmed|22383849]
