>TIGR02197 heptose_epim ADP-L-glycero-D-manno-heptose-6-epimerase; InterPro: IPR011912 Lipopolysaccharides (LPS) are glycolipids that consitutes the outer monolayer of the outer membranes of most Gram-negative bacteria . They consist of lipid A (endotoxin) which anchors LPS to the outer membrane, a non-repeating core oligosachharide, and an immunogenic O-antigen repeat polymer, which is an oligosaccharide of 1-40 units that variesbetween different strains of bacteria. Although the O-antigen and most of the core domain are not necessary for growth in the lab, they appear to help bacteria resist environmental stresses including the complement system and antibiotics. This family consists of examples of ADP-L-glycero-D-mannoheptose-6-epimerase, an enzyme involved in biosynthesis of the inner core of LPS in Gram-negative bacteria . This enzyme is homologous to UDP-glucose 4-epimerase (IPR005886 from INTERPRO) and belongs to the NAD dependent epimerase/dehydratase family. It participates in the biosynthetic pathway leading to incorporation of heptose, a conserved sugar, into the core region of LPS, performing the reaction shown below: ADP-D-glycero-D-manno-heptose = ADP-L-glycero-D-manno-heptose It is a homopentameric enzyme with each monomer composed of two domains: an N-terminal modified Rossman fold domain for NADP binding, and a C-terminal substrate binding domain.; GO: 0008712 ADP-glyceromanno-heptose 6-epimerase activity, 0050661 NADP binding, 0005975 carbohydrate metabolic process.
