TL;DR: DS 01 is a 29-residue-long peptide with a molecular mass of 2793 Da showing antibacterial properties against Gram-positive and Gram-negative bacteria in the range of 3-25 microm, suggesting its therapeutic value especially as an anti-T.

TL;DR: Six novel peptides called phylloseptins showing anti-bacterial and anti-protozoan activities were isolated from the skin secretion of the Brazilian tree-frogs and Phyllomedusa oreades, and Atomic force microscopy experiments indicated that the bacteriolytic properties of these peptides might be related to their disruptive action on the cell membrane.

TL;DR: The purification and characterization of a novel γ‐thionin from cowpea seeds with bactericidal activity against Gram‐positive and Gram‐negative bacteria is reported and the use of plant defensins in the construction of transgenic plants and also in the production of novel drugs with activity against human pathogens is discussed.

TL;DR: Six new antimicrobial peptides structurally related to the dermaseptin family have been isolated from the skin secretion of the amphibian Phyllomedusa hypochondrialis by de novo MS/MS experiments, Edman degradation, and cDNA sequencing.

TL;DR: In this paper, the presence of defense-related proteins from passion fruit (Passiflora edulis f. flavicarpa) seeds was investigated, and two proteins, named Pf1 and Pf2, were eluted in 0.1 and 0.2M of salt, respectively, and submitted to reverse phase chromatography in HPLC.
