โœฆ Synopsis


THREE FIGURES

Cyanide is known to retard cellular oxidations by inactivation of some of the enzymes concerned. Since luminescence in Cypridina results when luciferin is oxidized in the presence of luciferase, cyanide might be expected t o affect luciferase with consequent reduction of luminescence. Harvey ('17) and Van Schouwenburg ('38) found no visible effect of cyanide on a glowing extract of whole Cypsidina. Such a mixture, however, contains besides luciferin and luciferase, many impnrities which might selectively bind the cyanide. Experiments were, therefore, designed to study the effect of cyanide on partially purified luciferin and dialysed luciferase.
