ENZYME entry: EC 5.3.1.5

PURL: https://purl.expasy.org/enzyme/EC/5.3.1.5
Accepted Name
xylose isomerase
Alternative Name(s)
D-xylose aldose-ketose-isomerase
D-xylose isomerase
D-xylose ketoisomerase
D-xylose ketol-isomerase
Reaction catalysed
alpha-D-xylose = alpha-D-xylulofuranose
Comment(s)
  • Contains two divalent metal ions, preferably magnesium, located at different metal-binding sites within the active site.
  • The enzyme catalyzes the interconversion of aldose and ketose sugars with broad substrate specificity.
  • The enzyme binds the closed form of its sugar substrate (in the case of xylose and glucose, only the alpha anomer) and catalyzes ring opening to generate a form of open-chain conformation that is coordinated to one of the metal sites.
  • Isomerization proceeds via a hydride-shift mechanism.
