Description
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.
Applications
Pyruvate is critical for gluconeogenesis, lipogenesis, glyceroneogenesis, neurotransmitter biosynthesis and glucose-induced insulin, and is used to study these pr ocesses. The enzyme from Creative Enzymes has been used as a positive control during the assay of pyruvate carboxylase activity in cell-free extracts of Corynebacterium glutamicum.

Function
These data indicate that response of bovine PC gene to thermal stress is through promoter regulation and suggest that there are unique characteristics of bovine PC promoters that may contribute to the physiological response to thermal stress. These data indicate that pyruvate carboxylase promoter 1 is activated by fatty acids found in serum of feed-restricted cows. Expression of pyruvate carboxylase mRNA is part of the adaptive response to feed intake restriction
