absence of transmembrane domains, presence of hydrolase/acyltransferase domain with a distinct lipid-binding motif and a lysophospholipase domain, reduced phosphatidic acid in mutants suggests a role in phosphatidic acid biosynthesis, overexpression shows increase in phosphatidic acid and other phospholipids on organic solvent exposure, recombinant protein acylates lysophosphatidic acid, substrate preference analyzed, nearly no activity with lysophospholipids such as lysophosphatidylcholine (LPC), lysophosphatidylethanolamine (LPE), and lysophosphatidylserine (LPS) | Saccharomyces cerevisiae |
