Hygromycin-B kinase

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


 * ATP + hygromycin B $$\rightleftharpoons$$ ADP + 7"-O-phosphohygromycin

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.
