Data class Domain;
Predictors PROSITE; PS51415; XYLOSE_ISOMERASE
Name Xylose isomerase family
Function Xylose isomerase (EC 5.3.1.5) is an enzyme found in microorganisms and plants which catalyzes the interconversion of the aldo sugars D-xylose or D-glucose to the keto sugars D-xylulose and D-fructose. The catalytic activity requires magnesium, cobalt or manganese.
Scope(s) Eukaryota
Bacteria
Example(s) Q93RJ9 (XYLA_STROI); Q9FKK7 (XYLA_ARATH);
