The lipid bound to p60src, the transforming protein of Rous sarcoma virus, has been identified by gas and thin-layer chromatography as the 14-carbon saturated fatty acid, myristic acid. The protein can be labeled biosynthetically with either [3H]myristic acid or [3H]palmitic acid. Incorporation of
p21v-H-ras, the transforming protein of Harvey murine sarcoma virus, contains a covalently attached lipid. Using thin-layer chromatography, we identified the acyl group as the 16-carbon saturated fatty acid palmitic acid. No myristic acid was detected in fatty acids released from in vivo-labeled
Germ-free and conventional infant rats delivered by hysterectomy were reared artificially, using one of two diets--diet LNa (with a high saturated fatty acid content) and diet K 50 (with a high unsaturated fatty acid content). Animals reared for a short time (up to 5 days) after birth on the LNa
The membrane fluidity of cultured Yoshida sarcoma cells was determined under the culture condition in which various amounts of saturated and unsaturated fatty acids were supplemented to a serum-free medium containing defatted bovine serum albumin. The greater amount of unsaturated fatty acids was
Yoshida sarcoma cells were incubated with each of 4 different saturated and 17 different unsaturated fatty acid methyl and ethyl esters in order to modify the fatty acid composition of the cell membrane, and a possible correlation between the lipid fluidity of the cell membrane and the metastatic
p60src, the transforming protein kinase of Rous sarcoma virus, contains the 14-carbon saturated fatty acid, myristic acid, linked through an amide bond to the alpha-amino group of its NH2-terminal glycine residue. Myristic acid is known to be attached to four other eukaryotic proteins. In each case
