Enzyme Information

5.3.1.5
Xylose isomerase.
based on mapping to UniProt P24300
D-xylopyranose = D-xylulose.
-!- 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 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.
