Chains	Enzyme Name	Description	Catalytic Residues
A	streptopain M-CSA #598	Cysteine protease which is a virulance factor for many infectious diseases. It displays structural homology with papains despite having such low sequence identity with the superfamily that it merits being placed in a completely separate class.
