Protein sets from fully sequenced genomes. A cofactor is any non-protein substance required for a protein to be catalytically active. People with experience in Pyruvate Kinase Deficiency help solve this question. During glycolysis, the simple sugar glucose is broken down to produce adenosine triphosphate (ATP), the cell's main energy source. Pyruvate kinase is the last enzyme involved in the glycolytic process, transferring the phosphate group from phosphenol pyruvate to a waiting adenosine diphosphate (ADP) molecule, resulting in both adenosine triphosphate (ATP) and pyruvate. However, the specific role of both atoms in the catalytic event have not been thoroughly elucidated. is extremely low.

It has been shown that muscle pyruvate kinase (PK) responds hyperbolically to its substrate, PEP, but the liver form of the enzyme responds sigmoidally. Both pyruvate and lactate can be used to regenerate glucose as well. The first step is the nucleophilic attack of the PEP phosphorous atom by β-phosphoryl oxygen of ADP; this step displaces enolpyruvate while forming ATP. Pyruvate is modified by removal of a carboxyl group followed by oxidation, and then attached to … The PKLR gene tells the body how to make an enzyme called pyruvate kinase R, or PKR.
