WebJun 19, 2007 · When antisense lines of tobacco containing only 15% Fd-glutamate synthase activity were exposed to air, there was a 20-fold increase in glutamine, ammonia, and 2-oxoglutarate, whilst the glutamate concentration only fell by a maximum of 40% to 10 nmol mg −1 DW towards the end of the light period (Ferrario-Méry et al., 2002a, b). WebGlutamate dehydrogenase (GLDH, GDH) is an enzyme observed in both prokaryotes and eukaryotic mitochondria.The aforementioned reaction also yields ammonia, which in eukaryotes is canonically processed as a substrate in the urea cycle.Typically, the α-ketoglutarate to glutamate reaction does not occur in mammals, as glutamate …

WebDec 11, 2012 · The genome contains two putative open reading frames encoding a glutamate synthase (gdh1 and gdh2), only one open reading frame encoding the large subunit of a glutamate synthase (gltA) and two open reading frames each potentially encoding the small subunit of a glutamate synthase (gltB1 and gltB2). Glutamate synthase (also known as Glutamine oxoglutarate aminotransferase) is an enzyme and frequently abbreviated as GOGAT. This enzyme manufactures glutamate from glutamine and α-ketoglutarate, and thus along with glutamine synthetase (abbreviated GS) plays a central role in the regulation of nitrogen assimilation in photosynthetic eukaryotes and prokaryotes. This is of great importance as primary productivity in many marine environments is regulated by the avail…
