Summary
Protein Function
Caspases (cysteine-aspartic acid protease (Caspase) family) are a family of cysteine proteases that have important intracellular roles in inflammation and apoptosis. Activation of Caspases ensures that the cellular components are degraded in a controlled manner, carrying out cell death with minimal effect on surrounding tissues. Caspases exist as inactive proenzymes composed of a prodomain, a large protease subunit, and a small protease subunit. Activation of Caspases requires proteolytic processing at conserved internal aspartic residues to generate a heterodimeric enzyme consisting of the large and small subunits.
Cys Function & Property
The catalytic triad in Caspase-3 comprises Cys163, His121 and the backbone carbonyl oxygen atom of Arg64, which points towards the Nϵ atom of His121.
