Pyruvate dehydrogenase
The enzyme responsible for converting glucose to ethanol during fermentation is alcohol dehydrogenase. This enzyme facilitates the conversion of pyruvate to acetaldehyde and then to ethanol in the absence of oxygen.
Pyruvate cannot be directly converted into glucose in humans. This is because humans lack the enzyme pyruvate carboxylase needed for this conversion. Instead, pyruvate is normally converted into acetyl-CoA for entry into the citric acid cycle to produce energy.
The operation of the pyruvate dehydrogenase enzyme complex requires thiamine (B1), riboflavin (B2), niacin (B3), pantothenic acid (B5), and lipoic acid as cofactors for its activity. These vitamins are essential for the conversion of pyruvate to acetyl-CoA in the citric acid cycle.
This reaction is a phosphorylation reaction where phosphoenolpyruvate transfers a phosphate group to ADP to form pyruvate and ATP. It is catalyzed by the enzyme pyruvate kinase, an important step in glycolysis for ATP production.
Superoxide dismutase is an enzyme that converts free radicals like superoxide into hydrogen peroxide.

pyruvate
decarboxylation means removal of co2 from the reaction
PKD is caused by a deficiency in the enzyme, pyruvate kinase.
Thiamine (Vitamin B_1) is an important component of the pyruvate dehydrogenase complex--the enzyme complex which converts pyruvate to acetyl-CoA. This specific reaction is the "Link Reaction" which connects glycolysis and the citric acid cycle.
pyruvate carboxylase and phosphoenolpyruvate carboxykinase (PEPCK)
Renin is the enzyme that converts angiotensinogen into angiotensin I in the renin-angiotensin-aldosterone system.
Prothrombinase converts prothrombin into enzyme thrombin.
Pyruvate is an organic acid and is a ketone functional group. It is made up of glucose, acetyl co enzyme A, alanine, and ethanol.
I have the same question. I also need to know which microbe contains the enzyme phospoenolyruvate carboxylase. I am doing a project on this, and I need some answers. I guess we're in this together. :)
