ENZYME entry: EC 1.5.3.26

PURL: https://purl.expasy.org/enzyme/EC/1.5.3.26
Accepted Name
fructosyl amine oxidase (fructosamine-forming)
Reaction catalysed
an N-(1-deoxy-beta-D-fructopyranos-1-yl)amine + O2 + H2O = (1-deoxy-D-fructos-1-yl)amine + an aldehyde + H2O2
Comment(s)
  • Reducing sugars such as glucose react with amino groups in proteins via the spontaeous Maillard reaction, forming an unstable product that undergoes spontaneous rearrangement to a keto amine compound.
  • These reactions are known as glycation reactions, and the stable products are known as Amadori products.
  • This enzyme, characterized from a Pseudomonas sp. strain, cleaves the Amadori products at the alkylamine bond.
  • All other known fructosyl amine oxidases cleave the ketoamine bond (cf. EC 1.5.3.25).
