Snake venom toxins. The amino acid sequences of toxins b and d from Naja melanoleuca venom.

Two toxins have been isolated from the venom of the Forest cobra (Naja melanoleuca) and their amino acid sequences elucidated. Toxin b, a 71 amino acid residue molecule, is devoid of methionine and resembles toxin (x from Naja nivea venom both immunochemically and in amino acid sequence. Toxin d consists of 61 amino acid residues with alanine, phenylalanine, and leucine totally absent. Toxin d ...

Venom Down Under: Dynamic Evolution of Australian Elapid Snake Toxins

Despite the unparalleled diversity of venomous snakes in Australia, research has concentrated on a handful of medically significant species and even of these very few toxins have been fully sequenced. In this study, venom gland transcriptomes were sequenced from eleven species of small Australian elapid snakes, from eleven genera, spanning a broad phylogenetic range. The particularly large numb...

Snake Venom Toxins

A toxin, designated Fvrr has been isolated from the venom of the green mamba Dendroaspis angusticeps by ion exchange chromatography on Amberlite CG-50 and gel filtration on Sephadex G-50. . Toxin FvII consists of 61 amino acid residues, is devoid of phenylalanine and tryptophan, and is cross-linked by four intramolecular disulfide bridges. Immunochemically, toxin FvII is completely distinct fro...

Snake venom toxins. Purification, properties, and complete amino acid sequence of two toxins from Ringhals (Hemachatus haemachatus) venom.

Two toxins, designated Hemachatus haemachatus toxins II and IV, have been isolated from the venom of the South African Ringhals (H. haemachatus) by gradient chromatography on A.mberlite CG-50, and have been further purified by gel filtration on Sephadex G-50. The toxins are essentially homogeneous by free boundary electrophoresis, ultracentrifugation, and amino acid analyses. Toxins II and IV h...
