The staphostatin A polypeptide chain folds into a slightly deformed, eight-stranded beta-barrel, with strands beta-4 through beta-8 forming an antiparallel sheet while the N-terminus forms a a psi-loop motif. Members of this family constitute a class of cysteine protease inhibitors distinct in the fold and the mechanism of action from any known inhibitors of these enzymes [1].	Domain
