ENZYME entry: EC 3.5.1.46

PURL: https://purl.expasy.org/enzyme/EC/3.5.1.46
Accepted Name
6-aminohexanoate-oligomer exohydrolase
Alternative Name(s)
6-aminohexanoate-dimer hydrolase
6-aminohexanoic acid oligomer hydrolase
nylon-6 hydrolase
Reaction catalysed
  • [N-(6-aminohexanoyl)](n) + H2O = [N-(6-aminohexanoyl)](n-1) + 6-aminohexanoate
  • N-(6-aminohexanoyl)-6-aminohexanoate + H2O = 2 6-aminohexanoate
Comment(s)
  • 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 and EC 3.5.2.12.
