Isocitrate Dehydrogenase is an enzyme of the oxidoreductase class that catalyzes the conversion of isocitrate and NAD+ to yield 2-ketoglutarate, carbon dioxide, and NADH. It occurs in cell mitochondria. The enzyme requires Mg2+, Mn2+; it is activated by ADP, citrate, and Ca2+, and inhibited by NADH, NADPH, and ATP. The reaction is the key rate-limiting step of the citric acid (tricarboxylic) cycle.
Recombinant Saccharomyces Cerevisiae ICDH (NADP) derived from yeast host cells by using over-expression system, is full length same as designated ICD1 from Saccharomyces Cerevisiae. The N-terminal amino acid Phenylalanine residue next to Met is substituted with Alanine for overexpression.
The ICDH is purified by proprietary chromatographic techniques.
