A highly active phospholipase A2 in ram spermatozoa plasma membranes has been established. Phospholipase A2 was optimally active at pH 7.4 and was Ca2+ dependent. Low concentrations of K+ (25 mM) were found to inhibit phospholipase A2 activity, whereas higher concentrations induced enzyme reactivation. An inhibitory effect of Zn2+ has also been observed.
