Neomycin C transaminase

Neomycin C transaminase (EC 2.6.1.95, neoN (gene)) is an enzyme with systematic name 2-oxoglutarate:neomycin C aminotransferase. This enzyme catalyses the following chemical reaction

\rightleftharpoons

6'''-deamino-6'''-oxoneomycin C + L-glutamate

The reaction occurs in vivo in the opposite direction.
