| | rplB | LSU ribosomal protein L2P; One of the primary rRNA binding proteins. Required for association of the 30S and 50S subunits to form the 70S ribosome, for tRNA binding and peptide bond formation. It has been suggested to have peptidyltransferase activity; this is somewhat controversial. Makes several contacts with the 16S rRNA in the 70S ribosome. Belongs to the universal ribosomal protein uL2 family. (277 aa) |
| | rplW | LSU ribosomal protein L23P; One of the early assembly proteins it binds 23S rRNA. One of the proteins that surrounds the polypeptide exit tunnel on the outside of the ribosome. Forms the main docking site for trigger factor binding to the ribosome; Belongs to the universal ribosomal protein uL23 family. (94 aa) |
| | rplD | LSU ribosomal protein L1E; One of the primary rRNA binding proteins, this protein initially binds near the 5'-end of the 23S rRNA. It is important during the early stages of 50S assembly. It makes multiple contacts with different domains of the 23S rRNA in the assembled 50S subunit and ribosome. (207 aa) |
| | rplC | LSU ribosomal protein L3P; One of the primary rRNA binding proteins, it binds directly near the 3'-end of the 23S rRNA, where it nucleates assembly of the 50S subunit; Belongs to the universal ribosomal protein uL3 family. (207 aa) |
| | rpsJ | SSU ribosomal protein S10P; Involved in the binding of tRNA to the ribosomes. Belongs to the universal ribosomal protein uS10 family. (102 aa) |
| | hflX | GTP-binding protein; GTPase that associates with the 50S ribosomal subunit and may have a role during protein synthesis or ribosome biogenesis. Belongs to the TRAFAC class OBG-HflX-like GTPase superfamily. HflX GTPase family. (419 aa) |
| | efp-2 | Protein Translation Elongation Factor P; Involved in peptide bond synthesis. Stimulates efficient translation and peptide-bond synthesis on native or reconstituted 70S ribosomes in vitro. Probably functions indirectly by altering the affinity of the ribosome for aminoacyl-tRNA, thus increasing their reactivity as acceptors for peptidyl transferase. (185 aa) |
| | rplI | LSU ribosomal protein L9P; Binds to the 23S rRNA. (149 aa) |
| | yidC-2 | 60 kDa inner membrane protein; Required for the insertion and/or proper folding and/or complex formation of integral membrane proteins into the membrane. Involved in integration of membrane proteins that insert both dependently and independently of the Sec translocase complex, as well as at least some lipoproteins; Belongs to the OXA1/ALB3/YidC family. Type 2 subfamily. (279 aa) |
| | rpmH | COG0230 [J] Ribosomal protein L34; Belongs to the bacterial ribosomal protein bL34 family. (44 aa) |
