FunFam 9: Xylose isomerase

There are 1 EC terms in this cluster

Please note: EC annotations are assigned to the full protein sequence rather than individual protein domains. Since a given protein can contain multiple domains, it is possible that some of the annotations below come from additional domains that occur in the same protein, but have been classified elsewhere in CATH.

Note: The search results have been sorted with the annotations that are found most frequently at the top of the list. The results can be filtered by typing text into the search box at the top of the table.

EC Term Annotations Evidence
Xylose isomerase. [EC: 5.3.1.5]
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.
