Topology of the calmodulin-melittin complex.
Journal of molecular biology, 1998The topology of the Ca2+-calmodulin-melittin ternary complex has been investigated by a combined strategy which integrates limited proteolysis and cross-linking experiments with mass spectrometric methodologies. The rationale behind the methods is that the interface regions of two interacting proteins are accessible to the solvent in the isolated ...

The Journal of Membrane Biology, 1985
This paper describes experiments designed to explore interactions between human red blood cell membranes and melittin, the main component of bee venom. We found that melittin binds to human red cell membranes suspended in isotonic NaCl at room temperature, with an apparent dissociation constant of 3 X 10(-8) M and maximum binding capacity of 1.8 X 10(7)

Melittin: An allergen of honeybee venom
Journal of Allergy and Clinical Immunology, 1977The presence of serum IgE antibodies to melittin was tested by the radioallergosorbent test (RAST). Melittin, the principal protein of honeybee venom, was isolated by gel filtration on Sephadex G-75 and covalently bound to cyanogen bromide-activated microcrystalline cellulose.

Peptide inhibitors of melittin action
Journal of Protein Chemistry, 1996The sequence of peptides necessary to inhibit melittin-induced lysis was studied using 13 peptide analogues of the inhibitor Ac-IVIFDC-NH2. Although this inhibitor is a disulfide-linked dimer, inhibition was equally effective if the thiol SH was blocked or replaced by methionine or lysine.

Melittin interactions with adenylate cyclase
Biochimica et Biophysica Acta (BBA) - General Subjects, 1977Melittin, a basic polypeptide from bee venom, inhibits basal and thyrotropin-stimulated adenylate cyclase of beef thyroid membranes with a Ki approximately 10 micron. Although this property resides in the basic C-terminal and not the N-terminal portion of the molecule, inhibition is due primarily to its detergent-like nature rather than charge effects.

Melittin: from honeybees to superbugs
Applied Microbiology and Biotechnology, 2019The emergence of antibiotic-resistant bacteria, dubbed superbugs, together with relative stagnation in developing efficient antibiotics has led to enormous health and economic problems, necessitating the need for discovering and developing novel antimicrobial agents. In this respect, animal venoms represent a rich repertoire of pharmacologically active

Archives of Biochemistry and Biophysics, 1990
The (Na+ + K+)ATPase is inhibited by the bee venom polypeptide, melittin. KCl and NaCl protect the enzyme from melittin inhibition. Analysis of the K+ and Na+ protection against melittin inhibition suggested a kinetic model which was consistent with slowly reversible melittin binding, and mutually exclusive binding of melittin with K+ and Na ...

Biochimica et Biophysica Acta (BBA) - Biomembranes, 1991
The properties of melittin and a synthetic analogue, [Ala-14]melittin (P14A), in inducing reversible transitions between vesicles and micelles at the liquid-crystalline to gel phase transition temperature (Tm) in complexes with saturated phosphatidylcholines has been studied by deuterium NMR and freeze-fracture electron microscopy (EM).

Melittin-Binding of Troponin C
The Journal of Biochemistry, 1993Ca(2+)-dependent interaction between skeletal muscle troponin C and a bee venom melittin, which can be regarded as a mimic of the troponin C-binding peptide of troponin I, was investigated. Sephadex gel chromatography revealed that melittin bound to troponin C irrespective of the presence or absence of Ca2+ in 50 mM KCl and 50 mM Tris-HCl, pH 7.5.
