Glucose Dehydrogenase (GDH)
Tlhaloso
Glutamate Dehydrogenase (GDH) ke enzyme ea mitochondrial e etsang hore ho be le phepelo ea oxidative deamination ea glutamate ho a-ketoglutarate mme e sebetsa e le sehokelo sa bohlokoa lipakeng tsa anabolic le litsela tsa catabolic.Liphoofolo tse anyesang, GDH e tlas'a taolo ea allosteric mme e na le ts'ebetso e phahameng sebeteng, liphio, boko le manyeme.Mosebetsi oa GDH ka serum o ka sebelisoa ho khetholla pakeng tsa maloetse a sebete ka lebaka la ho ruruha ha sebete, tse sa bontšeng mosebetsi o phahameng oa serum GDH, le mafu a hlahisang hepatocyte necrosis, e leng se fellang ka serum e phahameng ea GDH.
Ts'ebetso ea GDH e khethoa ke tlhahlobo ea enzyme e kopantsoeng moo glutamate e jeoang ke GDH e hlahisang NADH, e sebetsanang le probe e hlahisang sehlahisoa sa colorimetric (450 nm) se lekanang le mosebetsi oa GDH o teng.Yuniti e le 'ngoe ea GDH ke palo ea enzyme e tla hlahisa 1.0 mmole ea NADH ka motsotso pH 7.6 ho 37 °C.
