CAPACITY FOR BIOSYNTHESIS OF PROSTAGLANDIN-RELATED COMPOUNDS: DISTRIBUTION AND PROPERTIES OF THE RATE-LIMITING ENZYME IN HYDROCORALS, GORGONIANS, AND OTHER COELENTERATES OF THE CARIBBEAN AND PACIFIC

Abstract

A convenient and reliable assay is described for PGEP synthetase, the rate-limiting enzyme determining the total capacity for biosynthesis of prostaglandin-related compounds. Results of such assays, performed withe fresh specimens under both field and laboratory conditions, newly identify several marine coelenterate species as potentially important resources of PGRCs for research and possible development. Properties of the typical marine coelenterate PGEP synthetase, and the reaction which this enzyme catalyzes, have been further characterized.
