EC |
2.6.1.95 |
Accepted name: |
neomycin C transaminase |
Reaction: |
neomycin C + 2-oxoglutarate = 6′′′-deamino-6′′′-oxoneomycin C + L-glutamate |
Other name(s): |
neoN (gene name) |
Systematic name: |
2-oxoglutarate:neomycin C aminotransferase |
Comments: |
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 1.1.3.44, 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 2.6.1.93, neamine transaminase. |
