The active site of phospholipase A2the active site. If one for example reacts the essential His 48 in phospholipase A. with an acylating reagent such as .-bromophenacyl-bromide all activity is lost. However the activity of phospholipase A. towards phospholipid micelles depends not only on the integrity of the active site itself, but

Lipomodulin, a naturally occurring phospholipase A2 inhibitory proteinyunsaturated fatty acid, and is often found to be arachidonic acid, a precursor of prostaglandins and leukotrienes (Van Den Bosh, 1980). The latter compounds are well known to have diverse biological actions such as inflammation, pain, fever and so on (Kuehl & Egan, 1980). Lysophosphatidylcholine, t

Renocortin: a phospholipase A2 inhibitory protein induced by anti-inflammatory steroids: pharmacology, ribonucleic acid (RNA) and new protein synthesis (Russo-Marie ., 1979). As it had been previously demonstrated that steroids were inhibiting PG synthesis by inhibiting the release of arachidonic acid from their membrane phospholipid stores, probably by inhibiting the enzyme responsible for the ph

Such profound effects of glucocorticoids are generally considered as ‘pharmacological actions’ since they are observed when amounts of steroids experimentally used in . or . studies are p

With a standard two-electrode voltage clamp the peak-to-peak baseline noise is at least 250 pA, so it was obviously impossible to resolve the currents through individual ion channels. The discovery by Neher & Sakmann of a
