(1->4)-N-acetyl-beta-D-glucosaminyl]n+m + reduced acceptor + O2 = [(1->4)-N-acetyl-beta-D-glucosaminyl]m-1-(1->4)-N-acetyl-2-deoxy-2-amino-D-glucono-1,5-lactone + [(1->4)-N-acetyl-beta-D-glucosaminyl]n + acceptor + H2O
(1->4)-N-acetyl-beta-D-glucosaminyl]n+m + reduced acceptor + O2 = [(1->4)-N-acetyl-beta-D-glucosaminyl]m-1-(1->4)-N-acetyl-2-deoxy-2-amino-D-glucono-1,5-lactone + [(1->4)-N-acetyl-beta-D-glucosaminyl]n + acceptor + H2O
(1) the initially formed D-glucono-1,5-lactone at the reducing end of the chitin chain quickly hydrolyzes spontaneously to the aldonic acid
