Ogdh activity
WebbRemarkably, unlike the activity of PDHC (Figure 1A), activity of ThDP-dependent 2-oxoglutarate dehydrogenase (OGDH) multienzyme complex (OGDHC) is not regulated in a daytime- or thiamine-dependent manner (Figure 3A), while the acetylated metabolic partner of OGDHC, GDH, demonstrates such regulation, according to the published data . Webb2-Oxoglutarate dehydrogenase (Ogdh) is an important mitochondria redox sensor that can undergo S-glutathionylation following an increase in H2O2 levels. Although S …
