## Abstract Pexiganan (GlyβIleβGlyβLysβPheβLeuβLysβLysβAlaβLysβLysβPheβGlyβLysβAlaβPheβValβLysβIleβLeuβLysβLys), a 22 amino acid peptide, is an analogue of the magainin family of antimicrobial peptides present in the skin of the African clawed frog. Conformational analysis of pexiganan was carried
It is now established that the circular dichroism in vibrational transitions (v.c.d.) of chiral molecules is a measurable phenomenon'. In v.c.d. measurements (3n -6) vibrational transitions can be probed, whereas, in conventional cd. measurements in the visible region, only a few electronic transit
Tripeptidesserve as model systems for understanding the so-called random-coil state of peptides and proteins. While it is well known that polyproline or proline-rich polypeptides adopt the very regular polyproline-II (PPII) or left-handed 3(1)-helix conformation, it was thus far not clear whether th
## Abstract A combination of ultraviolet (UV) and infrared (IR) absorption and circular dichroism (CD) spectroscopy was applied to investigate the structure and formation of large supramolecular DNAβprotein complexes. This combination of techniques was used to overcome limitations of UVβCD (electro
