چکیده

It is shown here that rat liver pyruvate dehydrogenase (PDH) kinase activator protein (KAP) catalyses ATP-dependent inactivation and [32P]phosphorylation of pig heart PDHE1 and of yeast (Saccharomyces cerevisiae) PDH complex devoid of PDH kinase activity, that fluorosulphonylbenzoyladenosine inactivates rat liver KAP and the intrinsic PDH kinase of rat liver PDH complex, and that KAP, like PDH kinase, is inactivated by thiol-reactive reagents. It is concluded that KAP is a free PDH kinase.

Kinase activator protein mediates longer-term effects of starvation on activity of pyruvate dehydrogenase kinase in rat liver mitochondria.

Starvation of rats for 48 h increased the activity of PDH (pyruvate dehydrogenase) kinase 2.2-fold in extracts of liver mitochondria, 2.9-fold in PDH complex partially purified therefrom by fractional precipitation, and 5-fold in PDH complex partially purified by gel filtration on Sephacryl S-300. A protein fraction was separated from PDH complex in extracts of rat liver mitochondria by gel fil...

kinase/activator in rat heart mitochondria Assay, effect of starvation, and effect of protein-synthesis inhibitors in starvation

Purified pig heart pyruvate dehydrogenase complex is denuded of its intrinsic pyruvate dehydrogenase kinase activity by sedimentation from dilute solution (60munits/ml). Kinase activity is restored by a supernatant fraction prepared by high-speed centrifugation of rat heart mitochondrial extracts; the factor responsible is referred to as kinase/activator. Kinase/activator was also assayed by it...

The Effects of Pyruvate Dehydrogenase Kinase 4 (PDK4) Inhibition on Metabolic Flexibility during Endurance Training in Skeletal Muscles of Streptozotocin-induced Diabetic Rats

Background:Metabolic flexibility is the capacity of a system to adjust fuel (primarily glucose and fatty acids) oxidation based on nutrient availability. Pyruvate Dehydrogenase Kinase 4 (PDK4) is one of the main enzymes that play a critical role in metabolic flexibility. In current study, we examined PDK4 inhibition along with exercise training (ET) on the gene expression of Es...

Regulation of pyruvate dehydrogenase in rat liver mitochondria by phosphorylation-dephosphorylation.

The percentage of total pyruvate dehydrogenase in the active nonphosphorylated form was measured in intact rat liver mitochondria after rapid separation of the mitochondria through silicone oil and extraction with glycerol buffer at 10”. The contents of ATP, ADP, Mg2+, and Ca2+ in the mitochondrial matrix of separated mitochondria were determined in parallel experiments. Mitochondria were incub...

Modulation of pyruvate dehydrogenase kinase activity in cultured hepatocytes by glucagon and n-octanoate.

The activity of pyruvate dehydrogenase kinase in extracts of mitochondria from rat hepatocytes cultured for 21 h in medium 199 was increased 2.5-fold by the presence of 55 nM-glucagon and 1 mM-sodium n-octanoate in the culture medium. The change was comparable with that induced in vivo by 48 h starvation. The potential contribution of branched-chain complex to estimates of PDH-complex activity ...
