CC -!- FUNCTION: Catalyzes the interconversion between ADP-D-glycero-beta-D-
CC manno-heptose and ADP-L-glycero-beta-D-manno-heptose via an
CC epimerization at carbon 6 of the heptose. {ECO:0000255|HAMAP-
CC Rule:MF_01601}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=ADP-D-glycero-beta-D-manno-heptose = ADP-L-glycero-beta-D-
CC manno-heptose; Xref=Rhea:RHEA:17577, ChEBI:CHEBI:59967,
CC ChEBI:CHEBI:61506; EC=5.1.3.20; Evidence={ECO:0000255|HAMAP-
CC Rule:MF_01601};
CC -!- COFACTOR:
CC Name=NADP(+); Xref=ChEBI:CHEBI:58349;
CC Evidence={ECO:0000255|HAMAP-Rule:MF_01601};
CC Note=Binds 1 NADP(+) per subunit. {ECO:0000255|HAMAP-Rule:MF_01601};
CC -!- PATHWAY: Nucleotide-sugar biosynthesis; ADP-L-glycero-beta-D-manno-
CC heptose biosynthesis; ADP-L-glycero-beta-D-manno-heptose from D-
CC glycero-beta-D-manno-heptose 7-phosphate: step 4/4. {ECO:0000255|HAMAP-
CC Rule:MF_01601}.
CC -!- PATHWAY: Bacterial outer membrane biogenesis; LPS core biosynthesis.
CC -!- SUBUNIT: Homopentamer. {ECO:0000255|HAMAP-Rule:MF_01601}.
CC -!- DOMAIN: Contains a large N-terminal NADP-binding domain, and a smaller
CC C-terminal substrate-binding domain. {ECO:0000255|HAMAP-Rule:MF_01601}.
CC -!- SIMILARITY: Belongs to the NAD(P)-dependent epimerase/dehydratase
CC family. HldD subfamily. {ECO:0000255|HAMAP-Rule:MF_01601}.
