Addtional InformationFUNCTION:Putative inhibitor of cysteine proteases. Does not inhibit papain. May protect the plant by inhibiting proteases of invading organisms.TISSUE SPECIFICITY:Tuber.SIMILARITY:Belongs to the protease inhibitor I3 (leguminous Kunitz-type inhibitor) family.CAUTION:Ref.1 postulates an inhibition of trypsin but the sequence homology points to a cysteine protease inhibitor.
