GLUD2

Glutamate dehydrogenase 2, mitochondrial, also known as GDH 2, is an enzyme that in humans is encoded by the GLUD2 gene.[3][4][5] This dehydrogenase is one of the family of glutamate dehydrogenases that are ubiquitous in life.

Function

Glutamate dehydrogenase 2 is localized to the mitochondrion and acts as a homohexamer to recycle glutamate during neurotransmission. The encoded enzyme catalyzes the reversible oxidative deamination of glutamate to alpha-ketoglutarate.[3]
