Enzyme Information

Lytic chitin monooxygenase.
based on mapping to UniProt Q838S1
((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.
