A kinetic investigation of the acyl-CoA oxidase reaction with the use of a novel spectrophotometric assay. Inhibition by acetyl-CoA CoA and FMN.

摘要

A direct-reading spectrophotometric assay for acyl-CoA oxidase activity is described. The assay is based on the strong absorption at 300 nm of deca-2-trans,4-cis-dienoyl-CoA, the product of oxidation of dec-4-cis-enoyl-CoA. By use of this assay, acetyl-CoA, CoA and FMN were found to be inhibitors of acyl-CoA oxidase, but with distinctly different kinetic characteristics.
