| chloramphenicol O-acetyltransferase | Chloramphenicol acetyltransferase (or CAT) is a bacterial enzyme (EC 2.3.1.28) that detoxifies the antibiotic chloramphenicol and is responsible for chloramphenicol resistance in bacteria. This enzyme covalently attaches an acetyl group from acetyl-CoA to chloramphenicol, which prevents chloramphenicol from binding to ribosomes. A histidine residue, located in the C-terminal section of the enzyme, plays a central role in its catalytic mechanism. Group: Enzymes. Synonyms: chloramphenicol acetyltransferase; chloramphenicol acetylase; chloramphenicol transacetylase; CAT I; CAT II; CAT III. Enzyme Commission Number: EC 2.3.1.28. CAS No. 9040-7-7. Storage: Store it at +4 ?C for short term. For long term storage, store it at -20 ?C?-80 ?C. Form: Liquid or lyophilized powder.

| Native Escherichia coli Chloramphenicol Acetyltransferase | Chloramphenicol acetyltransferase (or CAT) is a bacterial enzyme (EC 2.3.1.28) that detoxifies the antibiotic chloramphenicol and is responsible for chloramphenicol resistance in bacteria. This enzyme covalently attaches an acetyl group from acetyl-CoA to chloramphenicol, which prevents chloramphenicol from binding to ribosomes. A histidine residue, located in the C-terminal section of the enzyme, plays a central role in its catalytic mechanism. Applications: Chloramphenicol acetyltransferase from escherichia coli has been used in a study to assess the construction of a novel expression system in klebsiella pneumoniae and its application for 1,3-propanediol produ.etyl-CoA:chloramphenicol 3-O-acetyltransferase; CAT; 9040-07-7; chloramphenicol acetyltransferase; chloramphenicol acetylase; chloramphenicol transacetylase; CAT I; CAT II; CAT III.
