ARYLAMINE N-ACETYLTRANSFERASE (NAT) FROM SALMONELLA TYPHIMURIUM
Overview
Enzymes of the arylamine N-acetyltransferase (NAT) family are found in, species ranging from Escherichia coli to humans. In humans they are known, to be responsible for the acetylation of a number of arylamine and, hydrazine drugs, and they are strongly linked to the carcinogenic, potentiation of certain foreign substances. In prokaryotes their substrate, specificities may vary and members of the gene family have been linked to, pathways including amide synthesis during rifamycin production. Here we, report the crystal structure at 2.8 A resolution of a representative, member of this family from Salmonella typhimurium in the presence and, absence of a covalently bound product analog. The structure reveals, surprising mechanistic information including the presence of a Cys-His-Asp, ... [(full description)]
