streptogramin vat acetyltransferase [AMR Gene Family]

Accession ARO:3000453
Synonym(s)Streptogramin A acetyltransferase (SAT)
Definitionvat (Virginiamycin acetyltransferases) enzymes catalyze the transfer of an acetyl group from acetyl-CoA to the secondary alcohol of streptogramin A compounds, thus inactivating virginiamycin-like antibiotics and conferring resistance to these compounds.
