Lin and her lab use computational chemistry to provide information on the solution structures of cyclic peptides. [2] They recently successfully used molecular dynamics simulation with enhanced sampling methods to design well-structured cyclic peptides.
α-Amanitin Bacitracin Ciclosporin. Cyclic peptides are polypeptide chains which contain a circular sequence of bonds. [1] This can be through a connection between the amino and carboxyl ends of the peptide, for example in cyclosporin; a connection between the amino end and a side chain, for example in bacitracin; the carboxyl end and a side chain, for example in colistin; or two side chains ...
There are numerous types of peptides that have been classified according to their sources and functions. According to the Handbook of Biologically Active Peptides, some groups of peptides include plant peptides, bacterial/antibiotic peptides, fungal peptides, invertebrate peptides, amphibian/skin peptides, venom peptides, cancer/anticancer peptides, vaccine peptides, immune/inflammatory ...
Microviridins are cyclic N-acetylated trideca- and tetradecapeptides with ω-ester and/or ω-amide bonds. Lactone formation through glutamate or aspartate ω-carboxy groups and the lysine ε-amino group forms macrocycles in the final natural product.
Modelling biological systems is a significant task of systems biology and mathematical biology. [a] Computational systems biology [b] [1] aims to develop and use efficient algorithms, data structures, visualization and communication tools with the goal of computer modelling of biological systems.
Moreover, cR10, a cyclic poly-arginine CPP, enabled the endocytose independent transduction of antigen binding proteins through the cellular membrane with immediate bioavailability. Thereby, the authors of the study were able to deliver fluorescent antigen binding proteins into cells facilitating live-cell immunostaining. [ 58 ]

The stunting effect of kalata B1 cyclic peptide on growth and development of Helicoverpa punctigera, a caterpillar from the Lepidopteran order. [6]Cyclotides have been reported to have a wide range of biological activities, including anti-HIV, insecticidal, anti-tumour, antifouling, anti-microbial, hemolytic, neurotensin antagonism, trypsin inhibition, and uterotonic activities.
