A [auth E] | PF00082 | Subtilase family (Peptidase_S8) | Subtilase family | Subtilases are a family of serine proteases. They appear to have independently and convergently evolved an Asp/Ser/His catalytic triad, like that found in the trypsin serine proteases (see Pfam:PF00089). Structure is an alpha/beta fold containing a 7 ... | Domain |
