Unit Definition

One unit will convert 1.0 μmole of pyruvate and CO2 to oxalacetate per min at pH 7.8 at 30 °C.

Physical form

Solution in 50% glycerol containing 0.05 M Tris-HCl, pH 7.4, 2 mM magnesium acetate and 1 mM EDTA.


Pyruvate is critical for gluconeogenesis, lipogenesis, glyceroneogenesis, neurotransmitter biosynthesis and glucose-induced insulin, and is used to study these processes.

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.

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.
