CC   -!- FUNCTION: Mitochondrial glutamate dehydrogenase that converts L-
CC       glutamate into alpha-ketoglutarate. Plays a key role in glutamine
CC       anaplerosis by producing alpha-ketoglutarate, an important intermediate
CC       in the tricarboxylic acid cycle (By similarity). {ECO:0000250}.
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=H2O + L-glutamate + NAD(+) = 2-oxoglutarate + H(+) + NADH +
CC         NH4(+); Xref=Rhea:RHEA:15133, ChEBI:CHEBI:15377, ChEBI:CHEBI:15378,

CC   -!- SUBUNIT: Homohexamer.
CC   -!- SUBCELLULAR LOCATION: Mitochondrion matrix {ECO:0000250}.
CC   -!- SIMILARITY: Belongs to the Glu/Leu/Phe/Val dehydrogenases family.
CC       {ECO:0000305}.
