  2. Cyclic peptide - Wikipedia

    en.wikipedia.org/wiki/Cyclic_peptide

    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 ...

  3. Split-intein circular ligation of peptides and proteins

    en.wikipedia.org/wiki/Split-intein_circular...

    A number of natural antimicrobial peptides are cyclic, and the products of SICLOPPS are "increasingly viewed as ideal backbones for modulation of protein-protein interactions." [3] Circular peptides tend to be resistant to protease activity, and may be suitable for use as orally administered drugs.

  4. Arginylglycylaspartic acid - Wikipedia

    en.wikipedia.org/wiki/Arginylglycylaspartic_acid

    The structural rigidity of cyclic RGD peptides improves their binding properties and prevents degradation at the highly susceptible aspartic acid residue, thereby increasing their stability. [30] Many RGD derivative drugs and diagnostics are cyclized, including Eptifibatide, Cilengitide, CEND-1, and 18 F-Galacto-RGD, and 18 F-Fluciclatide-RGD.

  5. Cyclotide - Wikipedia

    en.wikipedia.org/wiki/Cyclotide

    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.

  6. Linusorb - Wikipedia

    en.wikipedia.org/wiki/Linusorb

    Linkage [1–#-NαC] Occurs between amino acid 1 and amino acid “#” through the α-amino group that a N-C cyclization of the core peptide. The en dash (–) is used and placed in square brackets. Modifications [#-Xaa,#-Xaa] The notation utilizes a prefix code of 3, 4 characters. Specifies the position and type of modified amino acids in the ...

  7. Cyclic glycine-proline - Wikipedia

    en.wikipedia.org/wiki/Cyclic_glycine-proline

    Cyclic glycine-proline (cGP) is a small neuroactive peptide that belongs to a group of bioactive 2,5-diketopiperazines (2,5-DKPs) and is also known as cyclo-glycine-proline. cGP is a neutral, stable naturally occurring compound and is endogenous to the human body; found in human plasma, breast milk and cerebrospinal fluid.
