Abstract
The full amino acid sequence of the acidic phospholipase A2 from Indian cobra (Naja naja naja) venom was determined and its tertiary structure examined by circular dichroism (CD). The sequence was aligned with other sequences of secreted phospholipase A2 from snakes of the genus Naja, using the progressive alignment method of Feng and Doolittle (J. Mol. Evol. (1987) 25, 351-360). The primary sequence of Naja naja naja phospholipases A2 shows up to 85% identity with the other acidic Naja phospholipase A2. CD studies indicate a 40-50% alpha-helical content in a tertiary structure which resists denaturation at high temperature, with or without chaotropic salts.Entities:
