PEPTIDE CHAINS WHICH CONTAIN A CIRCULAR SEQUENCE OF BONDS
Cyclic peptides; Peptides, cyclic; Cyclic polypeptides; Cyclic protein; Cyclic polypeptide; Cyclopeptides; Cyclopeptide; Peptide macrocycle
Cyclic peptides are polypeptide chains which contain a circular sequence of bonds. 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 or more complicated arrangements, for example in amanitin.
