The lipoate acetyltransferase (E2, M r 70 000) and protein X (M r 51 000) subunits of the bovine pyruvate dehydrogenase multienzyme complex (PDC) core assembly are ...
Reactions: pyruvate + coenzyme A + NAD + → acetyl-CoA + CO 2 + NADH (catalyzed by complex) acetyl-CoA + a [pyruvate dehydrogenase E2 protein] N 6-dihydrolipoyl-L-lysine ← a [pyruvate dehydrogenase E2 protein] N 6-S-acetyldihydrolipoyl-L-lysine + coenzyme A: Pathway: pyruvate decarboxylation to acetyl CoA I: Evidence The pyruvate dehydrogenase complex catalyzes, through five sequential reactions, the oxidative decarboxylation of pyruvate, an α-keto acid, to form a carbon dioxide molecules (CO2) and the acetyl group of acetyl-coenzyme A or acetyl-CoA, with the release of two electrons, carried by NAD. Question: Which Of The Following Is The Correct Information And Complete Reaction Equation Causing Lactoacidosis? (CHOOSE YOUR BEST ANSWER, OR CHOOSE ALL THAT APPLY - NO PARTIAL POINTS ARE GIVEN) O A. This Reaction Is Catalyzed By Pyruvate Dehydrogenase. The Sources Of The Active Coenzymes Are B5, Niacin, Riboflavin, Thiamin, And Lipoate. This study was undertaken to examine the mechanistic significance of two highly conserved residues positioned in the active site of pyruvate dehydrogenase kinase, Glu-243 and His-239. We used site-directed mutagenesis to convert Glu-243 to Ala, Asp, or Gln and His-239 to Ala. The resulting mutant kinases demonstrated a greatly reduced capacity for phosphorylation of pyruvate dehydrogenase. The ...
The dihydrolipoyl transacetylase (E2) component of A. vinelandii PDC and its lipoyl domain shows similar dynamic properties as revealed with fluoresce… The conversion occurs through a multistep sequence of reactions catalyzed by a complex of enzymes and cofactors called the pyruvate dehydrogenase complex. The process occurs in three stages , each catalyzed by one of the enzymes in the complex, as outlined in Figure 29.11 on page 1152. At low thiamine pyrophosphate concentrations the time-course of the reaction catalyzed by mammalian pyruvate dehydrogenase complex shows a lag period of some minutes when the reaction is started by either enzyme, pyruvate or thiamine pyrophosphate. However, started by CoASH or NAD+, the lag period disappears. An increase in enzyme concentration to 25 mU/ml causes a concomitant shortening of ...

Mammalian pyruvate dehydrogenase complex (PDC)1 cata-lyzes oxidative decarboxylation of pyruvate with concomitant formation of acetyl-CoA and NADH. Under physiological con-ditions this reaction is irreversible and, therefore, largely de-fines the metabolic fate of pyruvic acid and carbohydrate fuels in general (1).

The bacterial pyruvate dehydrogenase complex carries out conversion of pyruvate to acetyl-coenzyme A with the assistance of thiamin diphosphate (ThDP), several other cofactors, and three principal protein components, E1-E3, each present in multiple copies. The E2 component forms the core of the complexes, each copy consisting of variable numbers of lipoyl domains (LDs, lipoic acid covalently ...
