Identification
NameLysophospholipase 2
Synonyms
  • Phospholipase B 2
Gene NamePLB2
Enzyme Class
Biological Properties
General FunctionInvolved in metabolic process
Specific FunctionSequentially removes both fatty acyl groups from diacylglycerophospholipids and therefore has both phospholipase A and lysophospholipase activities. Substrate preference is phosphatidylserine > phosphatidylinositol > phosphatidylcholine > phosphatidylethanolamine
Cellular LocationSecreted, cell wall. Membrane; Lipid-anchor, GPI-anchor.
