DE   cathepsin B.
AN   cathepsin B1.
CA   Hydrolysis of proteins with broad specificity for peptide bonds.
CA   Preferentially cleaves -Arg-Arg-|-Xaa bonds in small molecule substrates
CA   (thus differing from cathepsin L). In addition to being an endopeptidase,
CA   shows peptidyl-dipeptidase activity, liberating C-terminal dipeptides.
CC   -!- An intracellular (lysosomal) enzyme.
CC   -!- Belongs to peptidase family C1.
