ADP-glyceromanno-heptose 6-epimerase
In enzymology, an ADP-L-glycero-D-manno-heptose 6-epimerase () is an enzyme that catalysis, catalyzes the chemical reaction :ADP-D-glycero-D-manno-heptose \rightleftharpoons ADP-L-glycero-D-manno-heptose Hence, this enzyme has one substrate (biochemistry), substrate, ADP-D-glycero-D-manno-heptose, and one product (chemistry), 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 List of enzymes, 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 (biochemistry), cofactor, NADP+ in a direct oxidation mechanism. Structural studies As of 2007, only one tertiary structure, structure has been solved for this class of enzymes, with the Protein Data Bank, PDB accession code .

Enzymology
Enzymes () are proteins that act as biological catalysts by accelerating chemical reactions. The molecules upon which enzymes may act are called substrates, and the enzyme converts the substrates into different molecules known as products. Almost all metabolic processes in the cell need enzyme catalysis in order to occur at rates fast enough to sustain life. Metabolic pathways depend upon enzymes to catalyze individual steps. The study of enzymes is called ''enzymology'' and the field of pseudoenzyme analysis recognizes that during evolution, some enzymes have lost the ability to carry out biological catalysis, which is often reflected in their amino acid sequences and unusual 'pseudocatalytic' properties. Enzymes are known to catalyze more than 5,000 biochemical reaction types. Other biocatalysts are catalytic RNA molecules, called ribozymes. Enzymes' specificity comes from their unique three-dimensional structures. Like all catalysts, enzymes increase the reaction ra ...
