PLA2 is a super-family of secretory and cytosolic enzymes; the latter are either Ca dependent or Ca independent. Enzymatically active PLA2 cleaves the sn-2 position of the glycerol backbone of phospholipids; secreted PLA2s have also been found to specifically bind to a variety of soluble and membrane proteins in mammals, including receptors. As a toxin, PLA2 is a potent presynaptic neurotoxin which blocks nerve terminals by binding to the nerve membrane and hydrolyzing stable membrane lipids. The products of the hydrolysis cannot form bilayers leading to a change in membrane conformation and ultimately to a block in the release of neurotransmitters. PLA2 may form dimers or oligomers. Bee venom PLA2 has fewer conserved disulfide bridges than most canonical PLA2s. Length = 97

PLA2 cleaves the sn-2 position of the glycerol backbone of phospholipids (PC or phosphatidylethanolamine), usually in a metal-dependent reaction, to generate lysophospholipid (LysoPL) and a free fatty acid (FA). The resulting products are either dietary or used in synthetic pathways for leukotrienes and prostaglandins. Often, arachidonic acid is released as a free fatty acid and acts as second messenger in signaling networks. Secreted PLA2s have also been found to specifically bind to a variety of soluble and membrane proteins in mammals, including receptors. As a toxin, PLA2 is a potent presynaptic neurotoxin which blocks nerve terminals by binding to the nerve membrane and hydrolyzing stable membrane lipids. The products of the hydrolysis (LysoPL and FA) cannot form bilayers leading to a change in membrane conformation and ultimately to a block in the release of neurotransmitters. PLA2 may form dimers or oligomers. Length = 83
1.1.4 from EC) (PLA2) is a small lipolytic enzyme that releases fatty acids from the second carbon group of glycerol. It is involved in a number of physiologically important cellular processes, such as the liberation of arachidonic acid from membrane phospholipids []. It plays a pivotal role in the biosynthesis of prostaglandin and other mediators of inflammation. PLA2 has four to seven disulphide bonds and binds a calcium ion that is essential for activity. Within the active enzyme, the alpha amino group is involved in a conserved hydrogen-bonding network linking the N-terminal region to the active site. The side chains of two conserved residues, His and Asp, participate in the catalytic network. Many PLA2's are widely distributed in snakes, lizards, bees and mammals. In mammals there are at least four forms: pancreatic, membrane-associated as well as two less well characterised forms. The venom of most snakes contains multiple forms of PLA2. Some of them are presynaptic neurotoxins which inhibit neuromuscular transmission by blocking acetylcholine release from the nerve termini. Some of the proteins in this family are allergens. Allergies are hypersensitivity reactions of the immune system to specific substances called allergens (such as pollen, stings, drugs, or food) that, in most people, result in no symptoms. A nomenclature system has been established for antigens (allergens) that cause IgE-mediated atopic allergies in humans [WHO/IUIS Allergen Nomenclature Subcommittee King T.P., Hoffmann D., Loewenstein H., Marsh D.G., Platts-Mills T.A.E., Thomas W. Bull. World Health Organ. 72:797-806(1994)]. This nomenclature system is defined by a designation that is composed of the first three letters of the genus; a space; the first letter of the species name; a space and an arabic number. In the event that two species names have identical designations, they are discriminated from one another by adding one or more letters (as necessary) to each species designation. The allergens in this family include allergens with the following designations: Api m 1.; GO: 0004623 phospholipase A2 activity, 0005509 calcium ion binding, 0016042 lipid catabolic process; PDB: 1POC_A.
