In enzymology, an ADP-L-glycero-D-manno-heptose 6-epimerase (EC 5.1.3.20) is an enzyme that catalyzes the chemical reaction
- ADP-D-glycero-D-manno-heptose ADP-L-glycero-D-manno-heptose
Hence, this enzyme has one substrate, ADP-D-glycero-D-manno-heptose, and one product, ADP-L-glycero-D-manno-heptose.
This enzyme belongs to the family of isomerases, specifically those racemases and epimerases acting on carbohydrates and derivatives. The systematic name of this enzyme class is ADP-L-glycero-D-manno-heptose 6-epimerase. This enzyme participates in lipopolysaccharide biosynthesis. It employs one cofactor, NADP+ in a direct oxidation mechanism.
