Description générale

Research area: Cell Signaling

Phosphoglycerate kinase (PGK), a glycolytic enzyme, is isolated from a broad variety of organisms. This typical hinge-bending monomeric enzyme is well-conserved among the three domains of life. The enzyme is made up of a single folded polypeptide chain that divides into two nearly identical domains, each linked by two -helices (-helices 7 and 14) and separated by a deep cleft. This arrangement gives the enzyme its distinctive bilobed structure.

Application

3-Phosphoglyceric Phosphokinase from baker′s yeast (S. cerevisiae) has been used:
  • to study low molecular weight GTP-binding proteins and mechanisms of inhibition of glyceraldehyde-3-phosphate dehydrogenase
  • in the coupled assay to measure the backward activity of purified rabbit skeletal muscle nicotinamide adenine dinucleotide (NAD+)-dependent glyceraldehyde3-phosphate dehydrogenase (GAPDH)
  • in the assay of glyceraldehyde-3-phosphate dehydrogenase

Actions biochimiques/physiologiques

3-Phosphoglyceric phosphokinase catalyzes the reversible transfer of a phosphate group from 1,3-diphosphoglycerate to ADP to generate ATP and 3-phosphoglycerate. 3-Phosphoglycerate phosphokinase activity is essential for glycolysis and gluconeogenesis. Phosphoglyceratekinase (PGK) plays a vital role in the glycolytic pathway by catalyzing one of the two ATP-producing reactions. It converts 1,3-bisphosphoglycerate (1,3BPGA) to 3-phosphoglycerate (3PGA). Additionally, it takes part in the process of gluconeogenesis by catalyzing the opposite reaction to create 1,3BPGA and adenosine diphosphate (ADP). Due to its participation in numerous processes other than energy metabolisms, such as pathogenesis, interaction with nucleic acids, tumorigenesis progression, cell death, and viral replication, PGK is also known as a moonlighting protein.

Définition de l'unité

One unit will convert 1.0 μmole of 1,3-diphosphoglycerate to 3-phosphoglycerate per min at pH 6.9 at 25 °C.

Forme physique

Crystalline suspension in 3.0 M (NH4)2SO4 and 0.04 M tetrasodium pyrophosphate solution, pH 8.0

S-nitrosothiols are nitric oxide (NO)-derived molecules found in biological systems. They have been variously discussed as both NO reservoirs and as major actors in NO-dependent, but cGMP-independent, signal transduction. Although S-nitrosation of specific cysteine residues has been suggested to represent

Based on the exquisite sensitivity, reproducibility and wide dynamic range of quantitative reverse-transcription real-time polymerase chain reaction (qRT-PCR), it is currently the gold standard for gene expression studies. Target gene expression is calculated relative to a stably expressed reference gene.
