IUBMB Enzyme Nomenclature


Accepted name: 6-aminohexanoate aminotransferase

Reaction: 6-aminohexanoate + 2-oxoglutarate = 6-oxohexanoate + L-glutamate

Other name(s): nylD (gene name)

Systematic name: 6-aminohexanoate:2-oxogutarate aminotransferase

Comments: The enzyme, characterized from the bacterium Arthrobacter sp. KI72, participates in the degradation of nylon-6. Glyoxylate can serve as an alternative amino group acceptor with similar efficiency.
