Hydrolyzes lysoglycerophospholipids to produce lysophosphatidic acid (LPA) and the corresponding amines (PubMed:25528375, PubMed:27637550). Shows a preference for 1-O-alkyl-sn-glycero-3-phosphocholine (lyso-PAF), lysophosphatidylcholine (lyso-PC) and N-acylethanolamine lysophospholipids (PubMed:25528375). Does not display glycerophosphodiester phosphodiesterase activity, since it cannot hydrolyze either glycerophosphoinositol or glycerophosphocholine (PubMed:25528375). 1-hexadecanoyl-sn-glycero-3-phosphocholine + H2O = 1-hexadecanoyl-sn-glycero-3-phosphate + choline + H(+) 1-O-hexadecyl-sn-glycero-3-phosphocholine + H2O = 1-O-hexadecyl-sn-glycero-3-phosphate + choline + H(+) 1-O-(1Z-octadecenyl)-sn-glycero-3-phospho-N-hexadecanoyl-ethanolamine + H2O = 1-O-(1Z-octadecenyl)-sn-glycero-3-phosphate + H(+) + N-hexadecanoylethanolamine H2O + N-(5Z,8Z,11Z,14Z-eicosatetraenoyl)-1-(9Z-octadecenoyl)-sn-glycero-3-phosphoethanolamine = 1-(9Z-octadecenoyl)-sn-glycero-3-phosphate + H(+) + N-(5Z,8Z,11Z,14Z-eicosatetraenoyl)-ethanolamine H2O + N,1-di-(9Z-octadecenoyl)-sn-glycero-3-phosphoethanolamine = 1-(9Z-octadecenoyl)-sn-glycero-3-phosphate + H(+) + N-(9Z-octadecenoyl) ethanolamine H2O + N-hexadecanoyl-1-(9Z-octadecenoyl)-sn-glycero-3-phosphoethanolamine = 1-(9Z-octadecenoyl)-sn-glycero-3-phosphate + H(+) + N-hexadecanoylethanolamine 1-hexadecanoyl-sn-glycero-3-phosphocholine + H2O = H(+) + hexadecanoate + sn-glycerol 3-phosphocholine Lysophospholipase D activity is stimulated by calcium. Loss of lysophospholipase D activity in presence of EDTA. Partially colocalized with CANX (PubMed:25528375). Highly expressed in stomach and kidney. In stomach detected in the glandular epithelium. Predominantly expressed in the stomach (at protein level). Belongs to the glycerophosphoryl diester phosphodiesterase family. Contaminating sequence. Sequence of unknown origin in the N-terminal part.
