EC 3.5.1.46 Details
EC number
3.5.1.46
Accepted name
6-aminohexanoate-oligomer exohydrolase
Reaction
(1) [N-(6-aminohexanoyl)]n + H2O = [N-(6-aminohexanoyl)]n-1 + 6-aminohexanoate;;(2) N-(6-aminohexanoyl)-6-aminohexanoate + H2O = 2 6-aminohexanoate
Other name(s)
6-aminohexanoate-dimer hydrolase, nylB (gene name), 6-aminohexanoic acid oligomer hydrolase (ambiguous), N-(6-aminohexanoyl)-6-aminohexanoate amidohydrolase, nylon-6 hydrolase (ambiguous)
Systematic name
N-(6-aminohexanoyl)-6-aminohexanoate exoamidohydrolase
CAS registry number
75216-15-8
Comment
The enzyme is involved in degradation of nylon-6 oligomers. It degrades linear oligomers of 6-aminohexanoate with a degree of polymerization of 2–20 by exo-type cleavage, removing residues sequentially from the N-terminus. Activity decreases with the increase of the polymerization number of the oligomer. cf. EC 3.5.1.117, 6-aminohexanoate-oligomer endohydrolase and EC 3.5.2.12, 6-aminohexanoate-cyclic-dimer hydrolase.
