EC 3.5.1.133 Details
EC number
3.5.1.133
Accepted name
Nα-acyl-L-glutamine aminoacylase
Reaction
an Nα-acyl-L-glutamine + H2O = L-glutamine + a carboxylate
Other name(s)
agaA (gene name), axillary malodor releasing enzyme, AMRE
Systematic name
Nα-acyl-L-glutamine amidohydrolase (carboxylate-forming)
Comment
Requires Zn2+. The enzyme, characterized from the bacterium Corynebacterium sp. Ax20, hydrolyses odorless Nα-acyl-L-glutamine conjugates of short- and medium-chain fatty acids, releasing axillary malodor compounds. While the enzyme is highly specific for the L-glutamine moiety, it is quite promiscuous regarding the acyl moiety. The two most common products of the enzyme’s activity in axillary secretions are (2E)-3-methylhex-2-enoate and 3-hydroxy-3-methylhexanoate.
