A dehydrogenase is an enzyme that oxidizes a substrate by transferring one or more protons and a pair of electrons to an acceptor, usually NAD/NADP or a flavin coenzyme such as FAD or FMN.

Examples

• aldehyde dehydrogenase
• acetaldehyde dehydrogenase
• alcohol dehydrogenase
• glutamate dehydrogenase (an enzyme that can convert glutamate to α-Ketoglutarate and vice versa).
• lactate dehydrogenase
• pyruvate dehydrogenase (a common enzyme which feeds the TCA Cycle in converting Pyruvate to Acetyl CoA)
• glucose-6-phosphate dehydrogenase (involved in the pentose phosphate pathway)
• glyceraldehyde-3-phosphate dehydrogenase (involved in glycolysis)

TCA cycle examples:

• isocitrate dehydrogenase
• alpha-ketoglutarate dehydrogenase
• succinate dehydrogenase
• malate dehydrogenase
