REFINEMENT PROTOCOL--flexible DETAILS--Using stereochemically and icosahedrally
restrained maximum likelihood refinement in REFMAC5, a representative subset of
the full atomic model with all neighbors present was built and refined to fit
the corresponding subset of the experimental map. Portions of the model whose
density resembled a structural homolog were identified and restrained to agree
with the homolog. Detailed atomic models were constructed in areas of
difference wherever the resolution of the map permitted. The
Fourier-amplitude-weighted average cosine of the phase discrepancy was tracked.
