Enzyme Information

3.4.22.1
Cathepsin B.
based on mapping to UniProt P07688
Hydrolysis of proteins with broad specificity for peptide bonds. Preferentially cleaves -Arg-Arg-|-Xaa bonds in small molecule substrates (thus differing from cathepsin L). In addition to being an endopeptidase, shows peptidyl-dipeptidase activity, liberating C-terminal dipeptides.
-!- An intracellular (lysosomal) enzyme. -!- Belongs to peptidase family C1.
