Steric requirements for the stimulation of glycosyltransferase activity by lysophosphatidylcholine.
1-Palmitoyl-sn-glycerol-3-phosphocholine and 3-palmitoyl-sn-glycerol-1-phosphocholine have been found to be equipotent in the stimulation of membrane-bound glycosyltransferases in microsomes of rat intestinal villus cells. This indicates that the stimulatory effect of lysophosphatidylcholine is not stereospecific, but that it may be related to a specific detergent property dependent upon the peculiar balance of hydrophilic and hydrophobic components in the molecule.
