rplB | LSU ribosomal protein L2p (L8e); 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. (276 aa) | ||||
efp | 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. (224 aa) | ||||
rplX | LSU ribosomal protein L24p (L26e); One of the proteins that surrounds the polypeptide exit tunnel on the outside of the subunit. (102 aa) | ||||
nusG | Transcription antitermination protein NusG; Participates in transcription elongation, termination and antitermination. (193 aa) |
