ENZYME entry: EC 1.1.1.333

PURL: https://purl.expasy.org/enzyme/EC/1.1.1.333

Accepted Name

decaprenylphospho-beta-D-erythro-pentofuranosid-2-ulose 2-reductase

Alternative Name(s)

decaprenylphospho-beta-D-ribofuranose 2'-epimerase

Reaction catalysed

trans,octa-cis-decaprenylphospho-beta-D-arabinofuranose + NAD(+) = trans,octa-cis-decaprenylphospho-beta-D-erythro-pentofuranosid-2-ulose + NADH + H(+)

Comment(s)

The reaction is catalyzed in the reverse direction.
The enzyme, isolated from the bacterium Mycobacterium smegmatis, is involved, along with EC 1.1.98.3, in the epimerization of trans,octacis-decaprenylphospho-beta-D-ribofuranose to trans,octacis- decaprenylphospho-beta-D-arabinoofuranose, the arabinosyl donor for the biosynthesis of mycobacterial cell wall arabinan polymers.
