Antimicrobial resistance and antimicrobial activity of plant-based antimicrobial peptides against bacteria

Letters in Animal Biology
Antimicrobial peptides (AMPs) are a class of short, usually positively charged, polypeptides which are widely used to overcome the threat of the antimicrobial resistance. The potential of the AMPs is increasing as a new class of antibiotics.

Cyclotides : a novel type of cytotoxic agents

, 2002
Cytotoxic activities of three naturally occurring macrocyclic peptides (cyclotides) isolated from the two violets, Viola arvensis Murr. and Viola odorata L., were investigated.

New Cyclotides Isolated from the Roots of Allexix batangae (Violaceae)

, 2019
Cyclotides are a very abundant class of plant peptides that display signi?cant sequence variability around a conserved cystine-knot motif and a head-to-tail cyclized backbone conferring them with remarkable stability.

Cyclotides : Tuning Parameters Toward Their Use in Drug Design

, 2012
Cyclotides are plant proteins with a unique topology, defined as the cyclic cystine knot motif. The motif endows cyclotides with exceptional chemical and biological stability. They also exhibit a wide range of biological activities including insecticidal,

Cyclotides evolve [Elektronisk resurs] : Studies on their natural distribution, structural diversity, and activity

, 2016
The cyclotides are a family of naturally occurring peptides characterized by cyclic cystine knot (CCK) structural motif, which comprises a cyclic head-to-tail backbone featuring six conserved cysteine residues that form three disulfide bonds. This unique
