The conformational substates B(I) and B(II) of the phosphodiester backbone in B-DNA are thought to contribute to DNA flexibility and protein recognition. We have studied by rapid scan FTIR spectroscopy the isothermal B(I)-B(II) transition on its intrinsic time scale. Correlation

Indolicidin, a cationic antimicrobial tridecapeptide amide, is rich in proline and tryptophan residues. Its biological activity is intensively studied, but the details how indolicidin interacts with membranes are not fully understood yet. We report here an in situ atomic force
Aaron P Podorieszach et al.

In the current study, indolicidin, a known antimicrobial originally isolated from bovine neutrophils, was modified with respect to hydrophobicity and tryptophan content to maximize bioactivity, and minimize cytotoxicity. Since indolicidin contains five tryptophans (very hydrophobic) of its total 13 amino
