OC Eukaryota; Fungi; Fungi incertae sedis; Microsporidia; Unikaryonidae; OC Encephalitozoon. OX NCBI_TaxID=284813; RN [1] RP NUCLEOTIDE SEQUENCE [LARGE SCALE GENOMIC DNA]. RC STRAIN=GB-M1; RX PubMed=11719806; DOI=10.1038/35106579; RA Katinka M.D., Duprat S., Cornillot E., Metenier G., Thomarat F., RA Prensier G., Barbe V., Peyretaillade E., Brottier P., Wincker P., RA Delbac F., El Alaoui H., Peyret P., Saurin W., Gouy M., Weissenbach J., RA Vivares C.P.; RT "Genome sequence and gene compaction of the eukaryote parasite RT Encephalitozoon cuniculi."; RL Nature 414:450-453(2001). CC -!- FUNCTION: Intracellular phospholipase B that catalyzes the double CC deacylation of phosphatidylcholine (PC) to glycerophosphocholine CC (GroPCho). Plays an important role in membrane lipid homeostasis. CC Responsible for the rapid PC turnover in response to inositol, elevated CC temperatures, or when choline is present in the growth medium (By CC similarity). {ECO:0000250}. CC -!- CATALYTIC ACTIVITY: CC Reaction=a 1-acyl-sn-glycero-3-phosphocholine + H2O = a fatty acid + CC H(+) + sn-glycerol 3-phosphocholine; Xref=Rhea:RHEA:15177, CC ChEBI:CHEBI:15377, ChEBI:CHEBI:15378, ChEBI:CHEBI:16870, CC ChEBI:CHEBI:28868, ChEBI:CHEBI:58168; EC=3.1.1.5; CC -!- ACTIVITY REGULATION: Inhibited by organophosphorus esters. CC {ECO:0000250}. CC -!- SUBCELLULAR LOCATION: Endoplasmic reticulum membrane {ECO:0000305}; CC Single-pass type I membrane protein {ECO:0000305}. CC -!- SIMILARITY: Belongs to the NTE family. {ECO:0000305}.
