A MANOMETRIC METHOD FOR MEASURING THE ACTIVITY OF THE CL. WELCHII LECITHINASE AND A DESCRIPTION OF CERTAIN PROPERTIES OF THIS ENZYME.

P C Zamecnik1, L E Brewster, F Lipmann.   

Abstract

A manometric method has been described for measurement of the activity of Cl. welchii lecithinase. The method depends on displacement of carbon dioxide from a bicarbonate-carbon dioxide-buffered medium by the phosphorylcholine liberated during the enzymatic hydrolysis.
