Using a recombinant phospholipase - D from the venom gland of L . intermedia ( LiRecDT1 ) in phospholipid - degrading kinetic experiments , we determined that this phospholipase - D mainly hydrolyzes synthetic sphingomyelin in a time - dependent manner , generating ceramide 1 - phosphate plus choline , as well as lysophosphatidylcholine , generating lysophosphatidic acid plus choline , but exhibits little activity against phosphatidylcholine .
 Chemical: sphingomyelin; Chemical: ceramide 1 - phosphate; Chemical: choline; Chemical: lysophosphatidylcholine; Chemical: lysophosphatidic acid; Chemical: choline; Chemical: phosphatidylcholine
