Application
The enzyme from Sigma has been used as a positive control during the assay of pyruvate carboxylase activity in cell-free extracts of Corynebacterium glutamicum.
Pyruvate is critical for gluconeogenesis, lipogenesis, glyceroneogenesis, neurotransmitter biosynthesis and glucose-induced insulin, and is used to study these processes.
Biochem/physiol Actions
Pyruvate carboxylase catalyzes the carboxylation of pyruvate to oxaloacetate. Pyruvate carboxylase is a mitochondrial protein that has a biotin prosthetic group that requiries magnesium or manganese and acetyl CoA.
Physical form
Solution in 50% glycerol containing 0.05 M Tris-HCl, pH 7.4, 2 mM magnesium acetate and 1 mM EDTA.
Preparation Note
Affinity purified
Other Notes
One unit will convert 1.0 μmole of pyruvate and CO2 to oxalacetate per min at pH 7.8 at 30 °C.

Besides its role as a carboxylase cofactor, biotin has a wide repertoire of effects on gene expression, development and metabolism. Pharmacological concentrations of biotin enhance insulin secretion and the expression of genes and signaling pathways that favor islet function in

In previous research, a thiamine-auxotrophic yeast for alpha-ketoglutaric acid (KGA) overproduction was screened in our laboratory and named Yarrowia lipolytica WSH-Z06 (CCTCC no. M207143). However, the high concentration of by-products (mainly pyruvate) limited its application on an industrial scale. To
