Abstract

In vitro assays are invaluable for the biochemical characterization of UDP-sugar:undecaprenyl-phosphate sugar-1-phosphate transferases. These assays typically involve the use of a radiolabeled substrate and subsequent extraction of the product, which resides in a lipid environment. Here, we describe the preparation of bacterial membranes containing these enzymes, a standard in vitro transferase assay with solvents containing chloroform and methanol, and two methods to measure product formation: scintillation counting and thin layer chromatography.
