Abstract
WE have found that an enzyme, phospolipase C, which has a very specific action in cleaving phosphatidylcholine (lecithin) at its ester linkage (between the α carbon of glycerol and the phosphoryl group of phosphorylcholine) stimulates active Na transport across frog skin in vitro. This action may provide both insight into the sort of processes involved in transepithelial Na transport and a model for the action of proteins induced by aldosterone 1,2. This hormone stimulates Na transport across epithelial membranes which, apart from the kidney tubules, include in vitro frog skin, and toad urinary bladder and colon3-7.
