New assay for the O-alkyl cleavage enzyme with alkyl-lysophospholipids as substrates

Cancer Res. 1985 Feb;45(2):616-8.

Abstract

The O-alkyl cleavage enzyme is important for the metabolism of cytotoxic alkyl-lysophospholipids. We have developed a simple new method for the determination of the enzyme activity which is based on the formation of water-soluble phosphate during the enzyme reaction. This is the first assay which avoids the use of radiolabeled substrates.
