A basic phospholipase A2 (PLA2) was isolated and purified from the venom of Bungarus fasciatus. Four kinds of enzymes, lysyl endopeptidase, endoproteinase Asp-N, endoproteinase Glu-C and trypsin, were employed to elucidate the complete primary structure by means of gas-phase sequencing. The amino-acid sequence reveals 118 amino-acid residues containing seven pairs of half-cystine. It has 78% and 61% structural identities with PLA2 from Bungarus multicinctus and Naja melanoleuca DE-II, respectively.
从银环蛇毒中分离并纯化出一种碱性磷脂酶A2（PLA2）。使用四种酶，即赖氨酰内肽酶、天冬氨酸蛋白酶Asp-N、谷氨酸蛋白酶Glu-C和胰蛋白酶，通过气相测序来阐明其完整的一级结构。氨基酸序列显示有118个氨基酸残基，包含七对半胱氨酸。它与多带银环蛇和黑曼巴蛇DE-II的PLA2分别具有78%和61%的结构同源性。
