  2. Peptide - Wikipedia

    en.wikipedia.org/wiki/Peptide

    A peptide hormone is a peptide that acts as a hormone. A proteose is a mixture of peptides produced by the hydrolysis of proteins. The term is somewhat archaic. A peptidergic agent (or drug) is a chemical which functions to directly modulate the peptide systems in the body or brain. An example is opioidergics, which are neuropeptidergics.

  3. Nisin - Wikipedia

    en.wikipedia.org/wiki/Nisin

    Nisin is a polycyclic antibacterial peptide produced by the bacterium Lactococcus lactis that is used as a food preservative.It has 34 amino acid residues, including the uncommon amino acids lanthionine (Lan), methyllanthionine (MeLan), didehydroalanine (Dha), and didehydroaminobutyric acid (Dhb).

    An example of this is the facially cationic peptide C18G, which was designed from the C-terminal domain of human platelet factor IV. [70] Currently, the most widely used antimicrobial peptide is nisin ; being the only FDA approved antimicrobial peptide, it is commonly used as an artificial preservative.

  5. Ribosomally synthesized and post-translationally modified ...

    en.wikipedia.org/wiki/Ribosomally_synthesized...

    This peptide consists of a core peptide segment which is typically preceded (and occasionally followed) by a leader peptide segment and is typically ~20-110 residues long. The leader peptide is usually important for enabling enzymatic processing of the precursor peptide via aiding in recognition of the core peptide by biosynthetic enzymes and ...

  6. Hydrolyzed protein - Wikipedia

    en.wikipedia.org/wiki/Hydrolyzed_protein

    Hydrolyzed protein is a solution derived from the hydrolysis of a protein into its component amino acids and peptides. While many means of achieving this process exist, the most common method is prolonged heating with hydrochloric acid, [1] sometimes with an enzyme such as pancreatic protease to simulate the naturally occurring hydrolytic process.

  7. Nonribosomal peptide - Wikipedia

    en.wikipedia.org/wiki/Nonribosomal_peptide

    The extended peptide is now attached to the current PCP-domain. Condensation - Cyclization : Sometimes the C-domain is replaced by a Cy-domain, which, in addition to the amide bond formation, catalyzes the reaction of the serine , threonine , or cysteine sidechain with the amide- N , thereby forming oxazolidines and thiazolidine , respectively.

  9. Oligopeptide - Wikipedia

    en.wikipedia.org/wiki/Oligopeptide

    An oligopeptide (oligo-, "a few"), is a peptide consisting of two to twenty amino acids, including dipeptides, tripeptides, tetrapeptides, and other polypeptides. Some of the major classes of naturally occurring oligopeptides include aeruginosins , cyanopeptolins , microcystins , microviridins , microginins , anabaenopeptins , and cyclamides .
