[Binding cytotoxin molecules from the venom of the Central Asian cobra with model membranes]. 1989

T F Aripov, and U M Beknazarov, and V G Omel'ianenko

Binding of Central Asia cobra venom cytotoxin with model membranes prepared from mixture of dilauroylphosphatidylcholine and cardiolipin, having different values of the molar ratio of the latter in the buffer medium with low (0.01 M NaCl) and high (2.0 M NaCl) ionic strength was studied using fluorescent probe ANS (1-anilinonaphthalene-8-sulfonate). The results obtained show that the binding of cytotoxin molecule with the membrane depends not only upon its surface charge but on lipid composition as well, which determines the structural organization of the membrane.

UI	MeSH Term	Description	Entries
D007700	Kinetics	The rate dynamics in chemical or physical systems.
D008567	Membranes, Artificial	Artificially produced membranes, such as semipermeable membranes used in artificial kidney dialysis (RENAL DIALYSIS), monomolecular and bimolecular membranes used as models to simulate biological CELL MEMBRANES. These membranes are also used in the process of GUIDED TISSUE REGENERATION.	Artificial Membranes,Artificial Membrane,Membrane, Artificial
D003603	Cytotoxins	Substances that are toxic to cells; they may be involved in immunity or may be contained in venoms. These are distinguished from CYTOSTATIC AGENTS in degree of effect. Some of them are used as CYTOTOXIC ANTIBIOTICS. The mechanism of action of many of these are as ALKYLATING AGENTS or MITOSIS MODULATORS.

D004546	Elapid Venoms	Venoms from snakes of the family Elapidae, including cobras, kraits, mambas, coral, tiger, and Australian snakes. The venoms contain polypeptide toxins of various kinds, cytolytic, hemolytic, and neurotoxic factors, but fewer enzymes than viper or crotalid venoms. Many of the toxins have been characterized.
