Figure 6

Analysis of domains and active site region of Apr-BO1. This protease showed two domains after InterPro Scan. (a) These domains are inhibitor 19 (ranging from amino acid residue 21–84) shown in purple and peptidase S8 domain (from 109 positions to 345th residue) represented in blue. (b) The subtilase ranges from 91 to 346 amino acids, and it is known that the S8 family possess a catalytic triad composed of Aspartate/Histidine/Serine, unlike the S53 family, which have glutamate instead of histidine as a part of this triad. ScanProsite tool revealed aspartate 118, histidine 150 and serine 307 as the catalytic triad residues. (c) This triad functions in a charge relay mechanism crucial for transforming substrate to products.
