Abstract

Summary: Puromycin is a potent inhibitor of bacterial protein synthesis, but puromycin-producing KCC S-0309 is tolerant to the antibiotic . Puromycin bound to both 30S and 50S ribosomal subunits from and inhibited polyuridylate-directed polyphenylalanine synthesis by the ribosomes. However, the organism possessed a novel puromycin-inactivating enzyme which acetylated the antibiotic at the 2″-NH group of the -methyltyrosine moiety.
