Post-translationally modified peptides
Web8 Apr 2024 · Peptides that mature in the endoplasmic reticulum or Golgi apparatus usually comprise fewer than 20 aa. Well-known post-translationally modified small peptides in … Post-translational modification (PTM) is the covalent and generally enzymatic modification of proteins following protein biosynthesis. This process occurs in the endoplasmic reticulum and the golgi apparatus. Proteins are synthesized by ribosomes translating mRNA into polypeptide chains, which may then undergo PTM to form the mature protein product. PTMs are important components in c…

Web21 Dec 2024 · The core region is post-translationally modified in a leader peptide-dependent and (or) independent manner to generate the mature RiPP. (B) Multiple copies of the recognition sequences and the following core peptides are distributed in the precursor peptide in some RiPPs. WebPeptides secreted as signals often undergo posttranslational modification and proteolytic processing to generate smaller peptides composed of approximately 10 amino acid residues. Such posttranslationally modified small-peptide signals constitute one of the largest groups of secreted peptide signals in plants.
