ENZYME entry: EC 4.3.2.6

Accepted Name
Gamma-L-glutamyl-butirosin B gamma-glutamyl cyclotransferase.
Reaction catalysed
Gamma-L-glutamyl-butirosin B <=> butirosin B + 5-oxoproline
Comment(s)
  • The enzyme catalyzes the last step in the biosynthesis of the aminoglycoside antibiotic butirosin B.
  • The enzyme acts as a cyclotransferase, cleaving the amide bond via transamidation using the alpha-amine of the terminal gamma-L- glutamate of the side chain, releasing it as the cyclic 5-oxoproline.
