ATP:hygromycin-B 4-O-phosphotransferase
Phosphorylates the antibiotic hygromycin B. Whereas the enzyme from Streptomyces hygroscopicus (EC 2.7.1.119; hygromycin-B 7''-O-kinase) catalyses the formation of 7''-O-phosphohygromycin B, this enzyme, found in Escherichia coli carrying a plasmid conferring resistance to hygromycin-B, forms 4-O-phosphohygromycin B.
