KEGG ENZYME: 3.4.22.53

ENZYME: 3.4.22.53

Entry

EC 3.4.22.53 Enzyme

Name

calpain-2;
calcium-activated neutral protease II;
m-calpain;
milli-calpain

Class

Hydrolases;
Acting on peptide bonds (peptidases);
Cysteine endopeptidases

Reaction(IUBMB)

Broad endopeptidase specificity

Comment

Type example of peptidase family C2. Requires Ca2+ at millimolar concentrations for activity. Cytosolic in animal cells. The active enzyme molecule is a heterodimer in which the large subunit contains the peptidase unit, and the small subunit is also a component of EC 3.4.22.52, calpain-1.

History

EC 3.4.22.53 created 1981 as EC 3.4.22.17, transferred 2003 to EC 3.4.22.53

Orthology

K03853
