Phospholipase D of rat brain synaptosomal membranes was tested with phosphatidylcholine as the substrate for its specificity in the use of primary alcohols as transphosphatidylation co-substrates. The efficiency of the reaction was related to the hydrophobicity and the membrane penetrating capacity of the alcohol molecule. Phosphatidylalcohol formation could be detected up to 1-octanol but not for alcohols with longer hydrocarbon chains (C(9), C(10)). With increasing alcohol concentration the transphosphatidylation activity of the phospholipase D reached an optimum and then declined abruptly. Alcohol concentrations required for maximal transphosphatidylation reaction generally decreased with increasing hydrophobicities of the alcohols. Nevertheless 1-butanol and 4-chloro-1-butanol were the most efficient cosubstrates, sharing identical optimal conditions. Transphosphatidylation works at the cost of phosphatidic acid formation. Phosphatidic acid itself was transformed to diacylglycerol, probably by a contaminating phosphatidic acid phosphohydrolase.
