Pathway: Metabolism (Homo sapiens)

Pathway: The citric acid (TCA) cycle and respiratory electron transport (Homo sapiens)
The metabolism of pyruvate provides one source of acetyl-CoA which enters the citric acid (TCA, tricarboxylic acid) cycle to generate energy and the reducing equivalent NADH. These reducing equivalents are re-oxidized back to NAD+ in the electron transport chain (ETC), coupling this process with the export of protons across the inner mitochondrial membrane. The chemiosmotic gradient created is used to

Pathway: Pyruvate metabolism and Citric Acid (TCA) cycle (Homo sapiens)
Pyruvate metabolism and the citric acid (TCA) cycle together link the processes of energy metabolism in a human cell with one another and with key biosynthetic reactions. Pyruvate, derived from the reversible oxidation of lactate or transamination of alanine, can be converted to acetyl CoA. Other sources of acetyl CoA include breakdown of free fatty acids and ketone bodies in the fasting state. Acetyl

Pathway: Regulation of pyruvate dehydrogenase (PDH) complex (Homo sapiens)
The mitochondrial pyruvate dehydrogenase (PDH) complex catalyzes the oxidative decarboxylation of pyruvate, linking glycolysis to the tricarboxylic acid cycle and fatty acid synthesis. PDH inactivation is crucial for glucose conservation when glucose is scarce, while adequate PDH activity is required to allow both ATP and fatty acid production from glucose. The mechanisms that control human PDH activit

Pathway: Pyruvate metabolism (Homo sapiens)
Pyruvate sits at an intersection of key pathways of energy metabolism. It is the end product of glycolysis and the starting point for gluconeogenesis, and can be generated by transamination of alanine. It can be converted by the pyruvate dehydrogenase complex to acetyl CoA (Reed and Hackert 1990) which can enter the TCA cycle or serve as the starting point for the syntheses of long chain fatty acids, s

Reaction: PDP-catalyzed dephosphorylation (activation) of phospho E1 alpha subunit (Homo sapiens)
Pyruvate dehydrogenase phosphatase (PDP) in the mitochondrial matrix catalyzes the hydrolytic removal of phosphate groups from phosphoserine residues in the E1 alpha subunit of the pyruvate dehydrogenase complex. The active form of PDP is a heterodimer of a catalytic subunit and a regulatory one. Two isoforms of the catalytic subunit have been identified and biochemically characterized (Huang et al. 19
