| malic acid dehydrogenase | <enzyme> An enzyme that catalyses the conversion of (s)-malate and NAD+ to oxaloacetate and NADH. Chemical name: (S)-Malate:NAD+ oxidoreductase Registry number: EC 1.1.1.37 (12 Dec 1998) |
| glycolic acid dehydrogenase | <enzyme> Enzyme from human liver converts glycolate to oxalate, acceptor not identified, not oxygen; free glyoxylate is not an intermediate Registry number: EC 1.1.- (26 Jun 1999) |
| norsolorinic acid dehydrogenase | <enzyme> Catalyses the conversion of norsolorinic acid to averantin Registry number: EC 1.1.1.- (26 Jun 1999) |
| isocitric acid dehydrogenase | <enzyme> An enzyme of the oxidoreductase class that catalyses the conversion of isocitrate and NAD+ to yield 2-ketoglutarate, carbon dioxide, and NADH. It occurs in cell mitochondria. The enzyme requires magnesium, mn2+; it is activated by ADP, citrate, and calcium, and inhibited by NADH, NADPH, and ATP. The reaction is the key rate-limiting step of the citric acid (tricarboxylic) cycle. (the NADP+ enzyme is EC 1.1.1.42.) Chemical name: Isocitrate:NAD+ oxidoreductase (decarboxylating) Registry number: EC 1.1.1.41 (12 Dec 1998) |

| 13-hydroxyoctadecadienoic acid dehydrogenase | <enzyme> Nad-dependent enzyme from rat colon mucosa; forms 13-oxooctadecadienoic acid; inhibited by disulfiram Registry number: EC 1.1.1.- Synonym: 13-hode dehydrogenase, 13-roh dehydrogenase (26 Jun 1999) |
| lactic acid dehydrogenase | <enzyme> An enzyme with 5 forms: LDH-1 is in the heart, its blood level can rise when heart muscle is damaged. Other forms can be found in the liver, brain, kidney, skeletal muscle and bone. A useful blood test in the evaluation of many disease processes, including heart attack, liver disease, muscular dystrophy and bone disease. (27 Sep 1997) |
