CC   -!- FUNCTION: Catalyzes the hydrolysis of 6-aminohexanoic acid cyclic dimer
CC       (1,8-diazacyclotetradecane-2,9-dione) to form the linear dimer 6-
CC       aminohexanoyl-6-aminohexanoic acid. {ECO:0000250}.
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=1,8-diazacyclotetradecane-2,9-dione + H2O = N-(6-
CC         aminohexanoyl)-6-aminohexanoate; Xref=Rhea:RHEA:16225,
CC         ChEBI:CHEBI:15377, ChEBI:CHEBI:16968, ChEBI:CHEBI:58798; EC=3.5.2.12;
CC   -!- PATHWAY: Xenobiotic degradation; nylon-6 oligomer degradation.
CC   -!- SUBUNIT: Homodimer. {ECO:0000250}.
CC   -!- SIMILARITY: Belongs to the amidase family. {ECO:0000305}.
