Thus, the two substrates of this enzyme are ATP and hygromycin B, whereas its two products are ADP and 7''-O-phosphohygromycin.
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:hygromycin-B 7"-O-phosphotransferase. This enzyme is also called hygromycin B phosphotransferase.
