Opis ogólny

Pyruvate kinase has a molar mass of 237,000 and exists as a tetramer. Each polypeptide chain of this tetramer has a molar mass of 57,200. The enzyme contains two identical catalytic particles called protomers. Each of these protomers contains two polypeptide chains. Each protomer contains one site each for Mn2+ and phosphoenolpyruvate.

Specyficzność

Specific activity: Approximately 200 U/mg at +25°C with PEP as the substrate.

Zastosowanie

Pyruvate Kinase (PK) has been used as a sample in ATPase Assays.
Pyruvate Kinase (PK) has been used in the kinase assay.

Działania biochem./fizjol.

Pyruvate kinase catalyzes the irreversible conversion of P-enolpyruvate and ADP to pyruvate and ATP with the utilization of a proton. The first step is the transfer of phosphate group from P-enolpyruvate to ADP with the formation of bound enolate of pyruvate and ATP. In the second step, a proton is added to enolate to generate the keto form of pyruvate. The enzyme also exhibits other activities, such as ATP- and bicarbonate-dependent ATPase, phosphorylation of fluoride and hydroxylamine, ATP-dependent phosphorylation of glycolate, and decarboxylation of oxaloacetate.

Jakość

Contaminants: <0.001% GK, <0.002% HK, “NADH oxidase”, and ATPase, each, <0.01% enolase, LDH, and myokinase, each.

Postać fizyczna

Solution in 50% glycerol (v/v), pH approximately 6

Uwaga dotycząca przygotowania

Activator: PK requires Mg2+ (or Mn2+, Co2+) and K+ (or NH4+, Rb+) for full activity.
