Membrane perturbing activities and structural properties of the frog-skin derived peptide Esculentin-1a(1-21)NH2 and its Diastereomer Esc(1-21)-1c: Correlation with their antipseudomonal and cytotoxic activity
Autor: Burkhard Bechinger, Vincenzo Luca, Maria Luisa Mangoni, Anirban Bhunia, Anirban Ghosh, Bruno Casciaro, Lorenzo Stella, Annalisa Bortolotti, Floriana Cappiello, Maria Rosa Loffredo, Nicole Harmouche
Publikováno v: Biochimica et Biophysica Acta (BBA) - Biomembranes. 1859:2327-2339
Antimicrobial peptides (AMPs) represent new alternatives to cope with the increasing number of multi-drug resistant microbial infections. Recently, a derivative of the frog-skin AMP esculentin-1a, Esc(1-21), was found to rapidly kill both the plankto

Publikováno v: Bortolotti, A, Wong, Y H, Korsholm, S S, Bahring, N H B, Bobone, S, Tayyab, S, Van De Weert, M & Stella, L 2016, ' On the purported "backbone fluorescence" in protein three-dimensional fluorescence spectra ', RSC Advances, vol. 6, no. 114, pp. 112870-112876 . https://doi.org/10.1039/c6ra23426g
In this study, several proteins (albumin, lysozyme, insulin) and model compounds (Trp, Tyr, homopolypeptides) were used to demonstrate the origin of the fluorescence observed upon their excitation at 220-230 nm. In the last 10 years we have observed
