ENZYME entry: EC

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) + H(2)O <=> (N-(6-aminohexanoyl))(n-1) + 6-aminohexanoate
  • N-(6-aminohexanoyl)-6-aminohexanoate + H(2)O <=> 2 6-aminohexanoate
  • 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 and EC
