Hygromycin B kinase

In enzymology, a hygromycin-B kinase (EC 2.7.1.119) is an enzyme that catalyzes the chemical reaction

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.
