GDP-mannose 3,5-epimerase

 Product Information

Cat #
MEVP-4762
Similar
Enzyme Commission Number
EC 5.1.3.18
Product Overview
High-quality enzyme products.
Well-established quality management system.
Reaction
(1) GDP-α-D-mannose = GDP-β-L-galactose
(2) GDP-α-D-mannose = GDP-β-L-gulose
Systematic Name
GDP-α-D-mannose 3,5-epimerase
Function
The enzyme catalyses the formation of the stable intermediate GDP-β-L-gulose as well as GDP-β-L-galactose. The reaction proceeds by C4′ oxidation of GDP-α-D-mannose followed by epimerization of the C5′ position to give GDP-β-L-4-dehydro-gulose. This intermediate is either reduced to give GDP-β-L-gulose or the C3′ position is epimerized to give GDP-β-L-4-dehydro-galactose, followed by C4′ reduction to yield GDP-β-L-galactose. Both products serve as intermediates in two different variants of plant L-ascorbate biosynthesis pathways.
