|Gene:||gdh||Accession Number: G-10249 (MetaCyc)|
Species: Neurospora crassa
Subunit composition of
glutamate dehydrogenase (NADP+) = [Gdh]6
glutamate dehydrogenase subunit = Gdh
Different species of yeasts and filamentous fungi, including Neurospora crassa, possess two glutamate dehydrogenases. One depends on NADP and has a biosynthetic role, whereas the other depends on NAD and catabolizes glutamate. Like the vertebrate enzymes, glutamate dehydrogenase (NADP+) of Neurospora crassa is a homohexamer, composed of 48.8 kDa subunits [Blumenthal73].
Unlike the vertebrate enzyme, the enzyme from Neurospora crassa exhibits very weak, if any, allosteric effects.
