Task: Answer Verification
Input (English): Question: Do three residues at the interface of factor XI ( FXI ) monomers augment covalent dimerization of FXI?
Answer: The data suggest that Leu284, Ile290 and Tyr329 in the interface of FXI monomers are essential for forming non-covalently bonded dimers that facilitate formation of a disulfide-bonded stable FXI dimer.
Output (English): yes
