IntEnz Enzyme Nomenclature


Accepted name:
neomycin C transaminase
Other name:
neoN (gene name)
Systematic name:
2-oxoglutarate:neomycin C aminotransferase



The reaction occurs in vivo in the opposite direction. Involved in the biosynthetic pathway of aminoglycoside antibiotics of the neomycin family. Works in combination with EC, 6'''-hydroxyneomycin C oxidase, to replace the 6'''-hydroxy group of 6'''-deamino-6'''-hydroxyneomycin C with an amino group. The enzyme, characterized from the bacterium Streptomyces fradiae, can also catalyse EC, neamine transaminase.
