Cloning and characterisation of novel cystatins from elapid snake venom glands
Biochimie, 2011Snake venoms contain a complex mixture of polypeptides that modulate prey homeostatic mechanisms through highly specific and targeted interactions. In this study we have identified and characterised cystatin-like cysteine-protease inhibitors from elapid snake venoms for the first time.

Preliminary studies on small molecular toxic components of elapid venoms
Toxicon, 1969Abstract Venoms of certain elapid snakes ( Naja , Hemachatus , Ophiophagus , Bungarus , Dendroaspis and Pseudechis ) were dialyzed against distilled water for 48 hr. The dialysates were compared by chromatography and electrophoresis. Unlike viperid and crotalid venoms ( Vipera , Bitis , Crotalus and Bothrops ), elapid venoms are highly ...

Conformational Properties of the Neurotoxins and Cytotoxins Isolated from Elapid Snake Venoms
Critical Reviews in Biochemistry, 1983The review will critically assess the information available on the conformation of homologous neurotoxins and cytotoxins isolated from Elapid snakes. Particular attention will be given to the dynamics of the molecules in solution because there is the possibility that defined intramolecular rearrangements are involved at the sites of action.

Immunological and histochemical identity of esterases and other antigens in elapid venoms
Toxicon, 1972Abstract Antibodies were prepared by hyperimmunizing rabbits with Naja naja, Bungarus fasciatus, Agkistrodon piscivorus and Apis mellifera (honeybee) venoms. By using immuno-electrophoresis, Ouchterlony technique and histochemical reactions, the identity of certain antigenic components and esterases in several elapid venoms has been demonstrated.

The preparation of 3-nitrotyrosyl derivatives of three elapid venom cardiotoxins
Biochimica et Biophysica Acta (BBA) - Protein Structure, 1980Nitration studies using tetranitromethane were conducted on the tyrosine residues of cardiotoxins, naja melanoleuca VII1, Naja haje annulifera VII1 and Hemachatus haemachates toxin 12B. Various partially and fully nitrated derivatives were formed. Analysis of the products of nitrating naja melanoleuca VII1 showed that the average relative reactivities ...

A comparative study of the homology of certain enzymes in elapid venoms
Comparative Biochemistry and Physiology Part B: Comparative Biochemistry, 1971Abstract 1. 1. Similar electrophoretic mobilities for esterases with identical substrate specificities have been shown for the venoms of several closely related elapidae. 2. 2. Two lactate dehydrogenase isozymes were shown for most Naja venoms with the slower migrating band (at alkaline pH's) showing constant mobility for all Naja species

Neutralization of tiger snake (Notechis scutatus) venom by serum from other Australian elapids
Toxicon, 1993Sera from four Australian elapids and one boidid (python) were tested for their ability to protect neonatal mice against the toxic action of tiger snake (Notechis scutatus) venom. Of the five serum samples tested, only serum from Pseudechis australis and Pseudechis porphyriacus were capable of neutralizing the tiger snake venom.

The selective S-alkylation of a methionine residue in an elapid venom cardiotoxin
International Journal of Biochemistry, 19871. The reaction of cardiotoxin with iodoacetamide or iodomethane at pH 3.0 afforded the corresponding methionine sulphonium derivatives. The major products were S-alkylated at Met-26 whilst the minor products were S-alkylated at both Met-24 and -26. 2. Reaction with iodoacetamide under denaturing conditions led to a reversal of the relative abundances ...

Histology, histochemistry, and emptying mechanism of the venom glands of some elapid snakes
Journal of Morphology, 1967AbstractThe venom glands of several species of elapid snakes are described. The main venom gland consists of many tubules which usually contain large amounts of secretion product. The accessory gland surrounds the entire venom duct and is usually composed of uniform mucous epithelium.
