Analysis Note

Protein determined by biuret.

Biochem/physiol Actions

Carnitine acetyltransferase maintains the cellular and mitochondrial levels of acetyl-CoA, a key cofactor required for oxidative metabolism, by catalyzing an equilibrium between acetyl-CoA and acetyl-L-carnitine, a storage form of activated acetate. Carnitine acetyltransferase also maintains the pool of acetyl-CoA required for neuronal and nonneuronal acetylcholine production.

Physical form

Crystalline suspension in 3.2 M (NH₄)₂SO₄ solution, 50 mM potassium phosphate, 1 mM dithiothreitol, pH 7.0

Unit Definition

One unit will convert 1.0 µmole of acetyl-L-carnitine and CoA to L-carnitine and acetyl-CoA per min at pH 8.0 at 25 °C.
