Peptide substrate

Peptide substrates are a broad class of molecules consisting of short amino acid sequences that serve as the reactants in enzyme-catalyzed reactions (IUPAC Gold Book, 2014). They are essential components in biological pathways where enzymes such as proteases, kinases, and phosphatases recognize specific peptide motifs to perform chemical modifications like cleavage or phosphorylation (Nature Education, 2010). In the context of pharmacology and drug discovery, "Peptide substrate" is not a specific therapeutic target but rather a functional designation for molecules acted upon by targets (ChEMBL, 2024). While specific peptides like Amyloid-beta or Angiotensin II are targeted in various diseases, the general category of peptide substrates is too broad for drug development (DrugBank Online, 2024). Consequently, this term is considered an incorrect or overly generic target designation in a structured database. Analysts should instead focus on the specific enzyme or the individual peptide molecule of interest to assess therapeutic relevance.
