EC 3.4.22.56 Details

show Brenda entry

EC number

3.4.22.56

Accepted name

caspase-3

Reaction

Strict requirement for an Asp residue at positions P1 and P4. It has a preferred cleavage sequence of Asp-Xaa-Xaa-Asp┼ with a hydrophobic amino-acid residue at P2 and a hydrophilic amino-acid residue at P3, although Val or Ala are also accepted at this position

Other name(s)

CPP32, apopain, yama protein

CAS registry number

169592-56-7

Comment

Caspase-3 is an effector/executioner caspase, as are caspase-6 (EC 3.4.22.59) and caspase-7 (EC 3.4.22.60) [5]. These caspases are responsible for the proteolysis of the majority of cellular polypeptides [e.g. poly(ADP-ribose) polymerase (PARP)], which leads to the apoptotic phenotype [3,5]. Procaspase-3 can be activated by caspase-1 (EC 3.4.22.36), caspase-8 (EC 3.4.22.61), caspase-9 (EC 3.4.22.62) and caspase-10 (EC 3.4.22.63) as well as by the serine protease granzyme B [1]. Caspase-3 can activate procaspase-2 (EC 3.4.22.55) [2]. Activation occurs by inter-domain cleavage followed by removal of the N-terminal prodomain [6]. Although Asp-Glu-(Val/Ile)-Asp is thought to be the preferred cleavage sequence, the enzyme can accommodate different residues at P2 and P3 of the substrate [4]. Like caspase-2, a hydrophobic residue at P5 of caspase-3 leads to more efficient hydrolysis, e.g. (Val/Leu)-Asp-Val-Ala-Asp┼ is a better substrate than Asp-Val-Ala-Asp┼ . This is not the case for caspase-7 [4]. Belongs in peptidase family C14.
