KEGG   ENZYME: 3.4.22.1Help
Entry
EC 3.4.22.1                 Enzyme                                 

Name
cathepsin B;
cathepsin B1 (obsolete);
cathepsin II
Class
Hydrolases;
Acting on peptide bonds (peptidases);
Cysteine endopeptidases
BRITE hierarchy
Reaction(IUBMB)
Hydrolysis of proteins with broad specificity for peptide bonds. Preferentially cleaves -Arg-Arg! bonds in small molecule substrates (thus differing from cathepsin L). In addition to being an endopeptidase, shows peptidyl-dipeptidase activity, liberating C-terminal dipeptides
Comment
An intracellular (lysosomal) enzyme in peptidase family C1 (papain family)
History
EC 3.4.22.1 created 1972
Orthology
K01363  cathepsin B
