Enzyme Information
| 2.7.1.163 |
Hygromycin B 4-O-kinase.
based on mapping to UniProt P00557
ATP + hygromycin B = ADP + 4-O-phosphohygromycin B.
-!- Phosphorylates the antibiotic hygromycin B. -!- Whereas the enzyme from Streptomyces hygroscopicus (EC 2.7.1.119) catalyzes 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. -!- Formerly EC 2.7.1.n6.
