title: Chromogenic assay for phospholipase C from Bacillus cereus.
abstract: A standard chromogenic assay for phosphatidylcholine determination has been modified in the development of a facile method for measuring the rate parameters (Km and Vmax) for phosphatidylcholine-preferring phospholipase C from Bacillus cereus (PLCBc). The assay is applied to the determination of the Ki for a known inhibitor of PLCBc.
