The primary structure of a phospholipase A2, with unique structural and functional characteristics, was determined. The large subunit has 108 amino acid residues, linked by a disulfide bridge to the small subunit, which contains 17 residues. Its gene was cloned from a cDNA library. The nucleotide sequence showed that the same RNA messenger encodes both subunits, separated only by a pentapeptide, that is processed during maturation.
