Molecule 1 - CASPASE-7 LARGE SUBUNIT
    Chains: A, C
    EC Number: 3.4.22.60
    Engineered: YES
    Expression System: ESCHERICHIA COLI
    Expression System Strain: BL21 (DE3)
    Expression System Taxid: 469008
    Gene: CASP7, MCH3
    Organism Common: HUMAN
    Organism Scientific: HOMO SAPIENS
    Organism Taxid: 9606
    Other Details: THIS STRUCTURE IS OF ACTIVE, CLEAVED CASPASE-7. A PROCASPASE-7 DIMER BECOMES ACTIVE, CLEAVED CASPASE-7 UPON PROTEOLYTIC PROCESSING, WHICH CLEAVES AFTER RESIDUES D23, D198 AND D206. THIS GENERATES FOUR CHAINS FROM EACH MONOMER. THE PRODOMAIN (RESIDUES 1- 23) AND THE INTERSUBUNIT LINKER (RESIDUES 199-206) ARE BOTH RELEASED. THUS ACTIVE, CLEAVED CASPASE-7 HAS TWO COPIES OF THE LARGE SUBUNIT (RESIDUES 24-198) AND TWO COPIES OF THE SMALL SUBUNIT (RESIDUES 206- 303). THE LARGE SUBUNIT OF CASPASE-7 CRYSTALLIZED HERE CONSISTED OF RESIDUES 24-198.
