General annotation (Comments)

Function

Catalyzes the interconversion between ADP-D-glycero-beta-D-manno-heptose and ADP-L-glycero-beta-D-manno-heptose via an epimerization at carbon 6 of the heptose By similarity.

Catalytic activity

ADP-D-glycero-D-manno-heptose = ADP-L-glycero-D-manno-heptose. HAMAP MF_01601

Cofactor

Binds 1 NADP+ per subunit By similarity.

Pathway

Nucleotide-sugar biosynthesis; ADP-L-glycero-beta-D-manno-heptose biosynthesis; ADP-L-glycero-beta-D-manno-heptose from D-glycero-beta-D-manno-heptose 7-phosphate: step 4/4. HAMAP MF_01601

Subunit structure

Homopentamer By similarity.

Domain

Contains a large N-terminal NADP-binding domain, and a smaller C-terminal substrate-binding domain By similarity.

Sequence similarities

Belongs to the sugar epimerase family. HldD subfamily.
