Trypsin catalytic triad motif

WebA 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 … WebTo avoid cleavage of substrates during these measurements, we used inactive variants of trypsin and u-PA whose catalytic serine S195 had been replaced by alanine. Differences in the K(d) values for binding of protein and peptide substrates closely approximate the large differences observed in the corresponding K(m) values.
