   Legend:   → Mismatch (orange background)
  - → Gap (green background, '-', border residues have a numbering label)
    → Modified Residue (blue background, lower-case, 'x' indicates undefined single-letter code, labelled with number + name)
  x → Chemical Group (purple background, 'x', labelled with number + name, e.g. ACE or NH2)
  extra numbering lines below/above indicate numbering irregularities and modified residue names etc., number ends below/above '|'

Chain A   (NYLC_FLASK | P07062)
molecular function
    GO:0019875    6-aminohexanoate-dimer hydrolase activity    Catalysis of the reaction: N-(6-aminohexanoyl)-6-aminohexanoate + H2O = 2 6-aminohexanoate.
    GO:0016787    hydrolase activity    Catalysis of the hydrolysis of various bonds, e.g. C-O, C-N, C-C, phosphoric anhydride bonds, etc. Hydrolase is the systematic name for any enzyme of EC class 3.
biological process
    GO:0019876    nylon catabolic process    The chemical reactions and pathways resulting in the breakdown of nylon, a polymer where the main polymer chain comprises recurring amide groups; these compounds are generally formed from combinations of diamines, diacids and amino acids.
