  • The triad is located in the active site of the enzyme, where catalysis occurs, and is preserved in all serine protease enzymes. (bionity.com)
  • Analysis of protonation characteristics showed, that such a negative potential in serine peptidases is essential to enhance the basicity of the catalytic histidine, which facilitates proton acceptance from serine. (uni-bayreuth.de)
  • But the negative potential further supports the concerted mechanism by increasing the nucleophilic potential of the catalytic serine. (uni-bayreuth.de)
  • These findings are in line with the experimentally measured inactivity of cysteine peptidases with their catalytic cysteine mutated into serine. (uni-bayreuth.de)
  • As expected, mutation of the catalytic cysteine to a serine led to inactivation, by which the substrate was bound non-processed within the binding pocket. (uni-bayreuth.de)
