Description
This enzyme, responsible for chloramphenicol resistance in bacteria by detoxifying the antibiotics chloramphenicol, transfers an acetyl group from acetyl-CoA to chloramphenicol, which prevents chloramphenicol from binding to ribosomes. The enzyme is a trimer of protein chains comprising of a left-handed β-helical domain and α small three a-helix domain. The binding sites for CoA and chloramphenicol are located in between the two protein chains. This structure does not contain ligands.
