General annotation (Comments)

Function

Catalyzes the reversible epimerization of D-ribulose 5-phosphate to D-xylulose 5-phosphate.

Catalytic activity

D-ribulose 5-phosphate = D-xylulose 5-phosphate.

Cofactor

Binds 1 divalent metal cation per subunit. Active with Co2+, Mn2+ and Zn2+ By similarity.

Pathway

Carbohydrate biosynthesis; Calvin cycle.

Subunit structure

Homohexamer. Ref.2

Subcellular location

Plastid › chloroplast thylakoid membrane.

Tissue specificity

Highest level of expression in leaves, whereas it is low in roots, tubers, and stems.

Sequence similarities

Belongs to the ribulose-phosphate 3-epimerase family.
