In enzymology a hygromycin-B kinase (EC 2.7.1.119) is an enzyme that catalyzes the chemical reactionATP + hygromycin B ADP + 7-O-phosphohygromycinThus 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.
