WebMar 17, 2024 · Cys, His, and Asp have additional potentially coordinating groups beyond the amino and carboxylic acid functional groups, specifically thiol in Cys, imidazole in His, and a second carboxylate in Asp. Gas-phase experiments comprised collision-induced dissociation (CID) of uranyl–amino acid complexes and competitive CID to assess the … Ser-His-Asp The Serine-Histidine-Aspartate motif is one of the most thoroughly characterised catalytic motifs in biochemistry. The triad is exemplified by chymotrypsin, a model serine protease from the PA superfamily which uses its triad to hydrolyse protein backbones. The aspartate is hydrogen bonded … See more A catalytic triad is a set of three coordinated amino acids that can be found in the active site of some enzymes. Catalytic triads are most commonly found in hydrolase and transferase enzymes (e.g. proteases See more Enzymes that contain a catalytic triad use it for one of two reaction types: either to split a substrate (hydrolases) or to transfer one portion of a … See more Nucleophile The side-chain of the nucleophilic residue performs covalent catalysis on the substrate. … See more The enzymology of proteases provides some of the clearest known examples of convergent evolution. The same geometric arrangement of triad residues occurs in over 20 separate enzyme superfamilies. Each of these superfamilies is the result of convergent … See more The enzymes trypsin and chymotrypsin were first purified in the 1930s. A serine in each of trypsin and chymotrypsin was identified as the catalytic nucleophile (by diisopropyl fluorophosphate modification) … See more The sophistication of the active site network causes residues involved in catalysis (and residues in contact with these) to be highly See more • Biology portal • Active site • Convergent evolution • Divergent evolution See more

WebJul 31, 2014 · The active site cysteine residue is embedded in a typical catalytic triad (Cys-His-Asp). An additional invariant Gln residue in close proximity stabilizes the transition state during catalysis. The substrate accesses the catalytic site through a shallow tunnel, in which conserved Trp residues are essential for positioning the di-glycine motif ...
