Studies on the venom components of the long-glanded coral snake, Maticora bivirgata.
Department of Chemistry, Faculty of Science, Tohoku University, Sendai, Japan.
The venom of the Asian long-glanded coral snake, Maticora bivirgata, was fractionated into five fractions, S1-S5, by passing through a Sephadex G-50 column. Fraction S2 contains two phospholipases A2, PLA2 I and PLA2 II, fraction S3 contains four cytotoxin homologues, maticotoxins A, C, D1 and D2, and fractions S4 and S5 contain a large amount (about 1 mg/specimen) of adenosine accompanied with smaller amounts of inosine and guanosine. The amino-terminal amino acid sequences of PLA2, I, PLA2 II and maticotoxin A suggest that Maticora bivirgata is closely related to Bungarinae, especially to genera Hemachatus and Naja.
