The effect of counterions on melittin aggregation [PDF]
Melittin, a surface-active polypeptide from bee venom, has an overall hydrophobic N-terminus, with basic residues clustered at the C-terminus. In aqueous solution melittin exists as a mixture of monomer and tetramer, the monomer adopting a predominantly random-coil configuration, whereas the tetramer is rich in α-helix.

Melittin interaction with sulfated cell surface sugars
Melittin is a 26-residue cationic peptide with cytolytic and antimicrobial properties. Studies on the action mechanism of melittin have focused almost exclusively on the membrane-perturbing properties of this peptide, investigating in detail the melittin-

Restricted mobility of the sole tryptophan in membrane-bound melittin [PDF]
In spite of numerous studies, there appears to be no consensus regarding the orientation and aggregation state of membrane-bound melittin. We report here the restricted environment of the sole tryptophan residue in membrane-bound melittin using ...

Effects of melittin on laying performance and intestinal barrier function of quails
: To study the effects of melittin on egg-laying performance and intestinal barrier of quails, 240 quails (aged 70 d) were randomly divided into 4 groups with 6 replicates (10 quails per replicate). They were fed with basal diet (group B), basal diet + 0.

Nature of Melittin-Phospholipid Interaction
Melittin, the major protein component of bee venom that possesses a strong hemolytic activity (1), is an amphipathic protein whose amino acid residues 1-20 are predominantly hydrophobic; residues 21-26 are hydrophilic. Determination of the molecular basis and specificity of the attractive forces involved in its interaction with membranes is essential ...

The structure of melittin [PDF]
The conformation of the 26‐residue polypeptide melittin has been studied using 1H‐NMR spectroscopy in methanolic solution. The 1H‐NMR spectrum of melittin has been assigned using two‐dimensional NMR techniques and the secondary structure has been calculated from nuclear Overhauser enhancement data using distance geometry and restrained molecular ...
