title: Fluorescence polarization assay for endothelin-converting enzymes.
abstract: The conversion of big endothelin to endothelin by alpha-chymotrypsin was determined by following its single Trp fluorescence polarization. This provides a novel, simple, fast, and sensitive identifying assay in the search for a native endothelin-converting enzyme.
