Chloramphenicol acetyltransferase Chloramphenicol acetyltransferase Chloramphenicol acetyltransferase acetylate the hydroxyl groups of chloramphenicol (Cm) from the acetyl-CoA. The acetylated Cm cannot bind ribosome 50S and is inactive. InterPro entry -> IPR001451 Chloramphenicol acetyltransferase (CAT) (EC:2.3.1.28) [1] catalyzes the acetyl-CoA dependent acetylation of chloramphenicol (Cm), an antibiotic which inhibits prokaryotic peptidyltransferase activity. Acetylation of Cm by CAT inactivates the antibiotic. A histidin…
