catalytic mechanism of caspase-7 consisting of three distinct kinetic steps leading to the protonation of the catalytic His144 and the deprotonation of Cys186, which is activated as a nucleophile, DFT computational investigation using crystal structure with PDB code 1FIJ, the catalytic dyad is formed by His144 and Cys186, existence of an alternative reaction channel leading directly from the initial complex to the peptide bond cleavage in a single kinetic step, detailed overview. The reaction pathway is characterized by a high energy barrier |
