Glucose Dehydrogenase (GDH)
Sharaxaada
Glutamate Dehydrogenase (GDH) waa enzyme mitochondrial kaas oo kicinaya deamination oksaydhiyaha ee glutamate ee a-ketoglutarate wuxuuna u adeegaa sida isku xirka muhiimka ah ee u dhexeeya waddooyinka anabolic iyo catabolic.Naasleyda, GDH waxay ku xiran tahay nidaaminta allosteric waxayna leedahay dhaqdhaqaaq sare oo beerka, kelyaha, maskaxda, iyo beeryarada.Dhaqdhaqaaqa GDH ee serum waxaa loo isticmaali karaa in lagu kala saaro cudurrada beerka sababtoo ah bararka beerka, taas oo aan muujinaynin dhaqdhaqaaqa sare ee serum GDH, iyo cudurrada keena hepatocyte necrosis, taas oo keenta serum GDH oo sarreeya.
Dhaqdhaqaaqa GDH waxa lagu go'aamiyaa qiimaynta ensaymka oo la isku daray kaas oo glutamate uu cunay GDH soo saaraysa NADH, kaas oo ka falcelinaya baadhitaan soo saaraya badeecad midabaysan (450 nm) oo u dhiganta hawsha GDH ee jirta.Hal unug oo GDH ah waa qadarka enzyme ka soo saari doona 1.0 mmle NADH daqiiqadii pH 7.6 at 37 °C
