Why is pyruvate converted into acetyl CoA prior to entering the Krebs Cycle? What does this conversion do to the pyruvate molecules? The Krebs Cycle: The Krebs Cycle (also known as the citric acid cycle) refers to the serious of process...
Endogenous pyruvate decarboxylase activity in yeast converts pyruvate to acetaldehyde, which is then converted to ethanol or to acetyl-CoA via acetate (see FIG. 1). Yeasts may have one or more genes encoding pyruvate decarboylase. For example, there is one gene encoding pyruvate decarboxylase in...
The pyruvate dehydrogenase complex catalyzes the conversion of pyruvate to acetyl-CoA. The first component (E1) converts pyruvate to bound acetaldehyde using thiamine diphosphate (ThDP) and Mg2+ as cofactors. There is no 3D structure of E1 available but those of other ThDP-dependent enzymes show...
The pyruvate dehydrogenase complex (PDHC) catalyzes the irreversible oxidation of pyruvate to acetyl CoA according to the reaction: $$Pyruvate + NA{{D}^{+}}+CoASHo Acetyl CoA + NADH + C{{O}_{2}}$$ The acetyl CoA formed is then either oxidized in the tricarboxylic acid cycle or used ...
Given the critical role of PDC E1 in the conversion of pyruvate to acetyl-CoA, we analysed the effect of STAT3 on PDC E1 activity in MEFs. STAT3−/− MEFs failed to induce PDC E1 activity in response to insulin (Fig. 3c). To estimate mitochondrial STAT3 activity, we constructed Cox4...
Each pyruvate is then oxidized into acetyl-CoA by the pyruvate dehydrogenase complex.

The enzyme (E-SH) achieves pyruvate conversion to acetyl-CoA via two distinct half-reactions (E-SH + pyruvate E-S-acetyl + formate; E-S-acetyl + CoA E-SH + acetyl-CoA), the first of which has been proposed to involve reversible homolytic carbon-carbon bond cleavage [J. Knappe et al...
Pyruvate is then oxidatively decarboxylated in a complex enzymatic system requiring the presence of lipoic acid, thiamine pyrophosphate, coenzyme A, NAD+ (DPN+), and pyruvic oxidase to form acetyl-CoA and NADH (DPNH). Pyruvate may follow a number of pathways, as outlined in Fig. 8. The ...
DCA is also known to improve the rate of the oxidative phosphorylation of glucose during glycolysis. The inhibition of PDK by DCA converts pyruvate to Acetyl-CoA by liberating the activity of PDH in the mitochondria. This has been shown to initiate normal oxidative phosphorylation through the TCA...
