ENZYME entry: EC

Accepted Name
Hygromycin B 4-O-kinase.
Alternative Name(s)
Hygromycin-B kinase.
Reaction catalysed
ATP + hygromycin B <=> ADP + 4-O-phosphohygromycin B
  • Phosphorylates the antibiotic hygromycin B.
  • Whereas the enzyme from Streptomyces hygroscopicus (EC 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.
