Proteins toxic to arthropods in the venom of elapid snakes
Journal of Insect Physiology, 1975It has been found that the lethal action of elapid snake venoms to arthropods (fly larvae and isopods) is due to proteic factors differing from the toxins which are strongly and specifically active on mammals. This conclusion was based on the following: (1) Lack of any correlation between the toxic activity on larvae, isopods, and mice of ten elapid

A comparative study of the biological properties of Australian elapid venoms
Comparative Biochemistry and Physiology Part C: Comparative Pharmacology, 19901. The hemorrhagic, procoagulant, anticoagulant, protease, phosphodiesterase, alkaline phosphomonoesterase, L-amino acid oxidase, acetylcholinesterase, arginine ester hydrolase, phospholipase A, 5'-nucleotidase and hyaluronidase activities of 39 samples of venoms from 13 species (15 taxa) of Australian elapids were determined and the Sephadex G-75 gel ...

Structure–function properties of venom components from Australian elapids
Toxicon, 1999A comprehensive review of venom components isolated thus far from Australian elapids. Illustrated is that a tremendous structural homology exists among the components but this homology is not representative of the functional diversity. Further, the review illuminates the overlooked species and areas of research.

Further studies on the mass of venom injected by Elapid snakes
Toxicon, 1983Further experimental studies to determine the mass of venom injected by medically-significant Australian elapids are reported. The use of a modified enzyme immunoassay technique to measure venom injected during snake bite is presented. The feeding biting pattern of the Australian eastern brown snake (Pseudonaja textilis) is described.

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
