Ribosome maturation factor; One of at least 4 proteins (Era, RbfA, RimM and RsgA/YjeQ) that assist in the late assembly stage of the 30S ribosomal subunit. An accessory protein needed during the final step in assembly of the 30S ribosomal subunit, for assembly of the head region (the 16S rRNA 3' domain). It may act while Era is associated and before RimP in 30S subunit assembly. Interacts with S19. Essential for efficient processing of 16S rRNA; a deletion mutant accumulates 17S rRNA. Deletions also do not assemble the head-associated ribosomal proteins correctly. May be needed both be [...]

50S ribosomal subunit protein L19; This protein is located at the 30S-50S ribosomal subunit interface. In the 70S ribosome it has been modeled to make two contacts with the 16S rRNA of the 30S subunit forming part of bridges B6 and B8. In the 3.5 A resolved structures L14 and L19 interact and together make contact with the 16S rRNA. The protein conformation is quite different between the 50S and 70S structures, which may be necessary for translocation.

30S ribosomal subunit protein S15; One of the primary rRNA binding proteins, it binds directly to 16S rRNA where it helps nucleate assembly of the platform of the 30S subunit by binding and bridging several RNA helices of the 16S rRNA. Binds to its own mRNA, stabilizing it 5-UTR and preventing its translation.

Translation elongation factor EF-Ts; Associates with the EF-Tu.GDP complex and induces the exchange of GDP to GTP. It remains bound to the aminoacyl-tRNA.EF- Tu.GTP complex up to the GTP hydrolysis stage on the ribosome. (Microbial infection) Promotes the tRNase activity of CdiA-CT from E.coli strain EC869 (CdiA-CT-EC869); required in vivo but less so in vitro. Probably loads charged tRNA onto EF-Tu, making more ternary GTP-EF-Tu-aa-tRNA complexes. The guanine nucleotide exchange factor capacity of this protein does not seem to be needed as no GTP hydrolysis occurs during tRNA cleavag [...]
