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 to the histidine, increasing the pKa of its imidazole nitrogen from 7 to around 12. This allows t… WebApr 25, 2016 · Catalytic Cys, His, and Asn are contributed by these two domains. These residues are located in the substrate binding cleft (Figure 1).
