Ribosome protection protein VmlR

UniProtKB accession:  P39115

Grouped By:  Matching UniProtKB accession

UniProtKB description:  Recognizes and binds in the vacant E-site of ribosomes stalled by some peptidyltransferase center (PTC)-targeting antibiotics. Makes contact with the PTC and both ribosomal subunits. Induces conformational changes in the P-site, which allows it to dislodge the antibiotic from its PTC binding site. Binds to ribosomes either directly following translation initation or subsequent to E tRNA release during elongation (PubMed:30126986). Involved in resistance to a narrow spectrum of antibiotics (the streptogramin A antibiotic virginiamycin M, the lincosamide antibiotic lincomycin and the pleuromutilin antibiotic tiamulin) (PubMed:16109936, PubMed:30126986).
