FunFam 4: Chitin binding protein

There are 1 EC terms in this cluster

Please note: EC annotations are assigned to the full protein sequence rather than individual protein domains. Since a given protein can contain multiple domains, it is possible that some of the annotations below come from additional domains that occur in the same protein, but have been classified elsewhere in CATH.

Note: The search results have been sorted with the annotations that are found most frequently at the top of the list. The results can be filtered by typing text into the search box at the top of the table.

EC Term Annotations Evidence
Lytic chitin monooxygenase. [EC: 1.14.99.53]
((1->4)-N-acetyl-beta-D-glucosaminyl)(n+m) + reduced acceptor + O(2) = ((1->4)-N-acetyl-beta-D-glucosaminyl)(m-1)-(1->4)-2-(acetylamino)-2- deoxy-D-glucono-1,5-lactone + ((1->4)-N-acetyl-beta-D-glucosaminyl)(n) + acceptor + H(2)O.
  • The enzyme cleaves chitin in an oxidative manner, releasing fragments of chitin with an N-acetylamino-D-glucono-1,5-lactone at the reducing end.
  • The initially formed lactone at the reducing end of the shortend chitin chain quickly hydrolyzes spontaneously to the aldonic acid.
  • In vitro ascorbate can serve as reducing agent.
