- ATP + viomycin ADP + O-phosphoviomycin
Thus, the two substrates of this enzyme are ATP and viomycin, whereas its two products are ADP and O-phosphoviomycin.
This enzyme belongs to the family of transferases, specifically those transferring phosphorus-containing groups (phosphotransferases) with an alcohol group as acceptor. The systematic name of this enzyme class is ATP:viomycin O-phosphotransferase. Other names in common use include viomycin phosphotransferase, and capreomycin phosphotransferase.
