PF00082Subtilase family (Peptidase_S8)Subtilase familySubtilases 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

PF05922Peptidase inhibitor I9 (Inhibitor_I9)Peptidase inhibitor I9This family includes the proteinase B inhibitor from Saccharomyces cerevisiae and the activation peptides from peptidases of the subtilisin family. The subtilisin propeptides are known to function as molecular chaperones, assisting in the folding of ...Domain
