pulvomycin

CHEBI:29668 ·resolve ·ANTIBACTERIAL ·EXACT SEEDED

Pulvomycin is a polyketide antibiotic that binds elongation factor Tu (EF-Tu) to inhibit protein biosynthesis by preventing the formation of the ternary complex (EF-Tu*GTP*aa-tRNA). Phenotypically, it was shown that pulvomycin sensitivity is dominant over resistance. — PMID:16734421
