Caspases contain
A) phosphorylated tyrosines when activated.
B) death domains.
C) an active site cysteine residue.
D) SODD.

Question

Quizplus · Accepted Answer

Caspases have an active site cysteine residue, which is essential for their proteolytic activity during apoptosis. None of the other options are correct - caspases do not contain phosphorylated tyrosines when activated, death domains are found in death receptors and not caspases, and SODD is an inhibitor of death receptor signaling and not a component of the caspase machinery.
