Phospholipase A of snake venoms. I. Isolation and molecular properties of isoenzymes from Naja naja and Vipera russellii venoms.

A combination of narrow range isoelectric focusing, electrophoresis on polyacrylamide gel, and gel exclusion on Sephadex reveals the presence of at least 9, possibly 11 isoenzymes of phospholipase A in Naja naja (cobra) venom. Their isoelectric points range from pH 4.60 to 5.66 and their molecular weights from 8,500 to 20,200. The most abundant form (isoelectric point = pH 4.95) has been isolat...

Enzyme inhibitions by Snake Venoms

1. Chromatography on silica gel, combined with infrared spectrometry, has been used to analyse mixtures of bile acids. 2. The results obtained by applying this method to an ox bile-salt preparation are described. Methyl lithocholate (methyl 3-hydroxycholanate) (1.8 mg.), methyl deoxycholate (methyl 3:12-dihydroxycholanate) (38 mg.), methyl chenodeoxycholate (methyl 3:7-dihydroxycholanate) (0-6 ...
