CAP is a heterodimer containing a small 28kDa regulatory subunit which is identical for all CAPs and a large 80kDa catalytic subunit. CAP undergoes conformational change upon binding of Ca+2 ions resulting in closing of its active site cleft and activation as a cysteine protease. <ref>PMID:11893336</ref> | CAP is a heterodimer containing a small 28kDa regulatory subunit which is identical for all CAPs and a large 80kDa catalytic subunit.
