ENZYME entry: EC 1.14.99.55

PURL: https://purl.expasy.org/enzyme/EC/1.14.99.55
Accepted Name
lytic starch monooxygenase
Alternative Name(s)
LPMO
Reaction catalysed
starch + reduced acceptor + O2 = D-glucono-1,5-lactone-terminated malto-oligosaccharides + short-chain malto-oligosaccharides + acceptor + H2O
Comment(s)
  • The enzyme cleaves starch in an oxidative manner.
  • It releases fragments of starch with a D-glucono-1,5-lactone at the reducing end.
  • The initially formed alpha-D-glucono-1,5-lactone at the reducing end of the shortend amylose chain quickly hydrolyzes spontaneously to the aldonic acid.
  • In vitro ascorbate has been found to be able to serve as reducing agent.
