ENZYME entry: EC 2.6.1.93

Accepted Name
Neamine transaminase.
Alternative Name(s)
Glutamate--6'-dehydroparomamine aminotransferase.
Reaction catalysed
Neamine + 2-oxoglutarate <=> 6'-dehydroparomamine + L-glutamate
Comment(s)
  • The reaction occurs in vivo in the opposite direction.
  • Involved in the biosynthetic pathways of several clinically important aminocyclitol antibiotics, including kanamycin B, butirosin, neomycin and ribostamycin.
  • Works in combination with EC 1.1.3.43 to replace the 6'-hydroxy group of paromamine with an amino group.
  • The enzyme from the bacterium Streptomyces kanamyceticus can also catalyze EC 2.6.1.94, which leads to production of kanamycin A.
  • The enzyme from the bacterium Streptomyces fradiae can also catalyze EC 2.6.1.95, leading to production of neomycin C.
