... gene,namely, SPO14. Another HKD family gene found in the yeast genome is PEL1/PGS1, encoding phosphatidylglyc-erol phosphate synthase [32]. It is therefore highly likely thatyeast PtdEtn-PLD is encoded ... Biol. Chem. 274, 11 824 11 8 31. 32. Chang, S.C., Heacock, P .N. , Clancey, C.J. & Dowhan, W. (19 98) The PEL1 gene (renamed PGS1) encodes the phosphatidylgly-cero-phosphate synthase of Saccharomyces ... family,but the gene that encodes it has not been identified yet. In the present study we have further characterized the cytosolic and membrane-bound forms of yeast PtdEtn-PLD and examined the regulation...
