Carnitine Acetyltransferase from pigeon breast muscle

ammonium sulfate suspension, ≥70 units/mg protein

Synonym: Acetyl-Co-A:carnitine-O-acetyltransferase, CrAT

Purchase

Description

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.

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.

Physical form

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

Ammonium Sulfate Suspensions - Technical Note

Note that for an ammonium sulfate suspension, most of the enzyme will be in solid form. It is likely that only negligible amounts of enzyme will be in the ammonium sulfate solution.
