| Abstract: | We have investigated the occurrence of protein-fatty acid acylation by metabolic incorporation of 3H]myristic and 3H]palmitic acids in Physarum polycephalum. We show that this organism contains fatty acylated proteins with mainly myristic acid covalently attached in alkali-stable linkages, probably amides. We find no evidence for ester-linked fatty acids, in contrast to the situation in vertebrate cells. |
