ENZYME entry: EC 1.14.99.54

PURL: https://purl.expasy.org/enzyme/EC/1.14.99.54
Accepted Name
lytic cellulose monooxygenase (C1-hydroxylating)
Alternative Name(s)
LPMO
lytic polysaccharide monooxygenase
Reaction catalysed
[(1->4)-beta-D-glucosyl]n+m + reduced acceptor + O2 = [(1->4)-beta-D-glucosyl]m-1-(1->4)-D-glucono-1,5-lactone + [(1->4)-beta-D-glucosyl]n + acceptor + H2O
Comment(s)
  • This enzyme, found in fungi and bacteria, cleaves cellulose in an oxidative manner.
  • The cellulose fragments that are formed contain a D-glucono-1,5- lactone residue at the reducing end, which hydrolyzes quickly and spontaneously to the aldonic acid.
  • The electrons are provided in vivo by the cytochrome b domain of EC 1.1.99.18.
  • Ascorbate can serve as the electron donor in vitro.
