Table II. Heavy atom phasing statistics.
Data set | pH | Resolution (Å) | Rderiva | No. of heavy atom sites | RCullisb | Phasing power |
---|---|---|---|---|---|---|
K2HgCl2 | 4.5 | 2.8 | 0.16 | 4 | 0.75 | 2.0 |
K2HgCl2 | 6.0 | 2.8 | 0.32 | 10 | 0.78 | 1.8 |
KAuCl4 | 4.5 | 2.8 | 0.12 | 10 | 0.83 | 1.4 |
K2HgCl2/KAuCl4 | 4.5 | 2.8 | 0.24 | 8 | 0.78 | 2.2 |
aRderiv = Σ|FPH – FP|/ΣFP
bRCullis = Σ||FPH ± FP| – FH (calc)/Σ|FPH ± FP| (for centric reflections only).
