Crystal parameters and refinement quality statistics.

Values in parentheses correspond to the highest resolution shell.aRsym = ∑h ∑i |Ihi -〈Ih〉|/∑h ∑i 〈Ih〉, where Ihi is the ith observation of reflection h and〈Ih〉is the weighted average intensity for all observations i of reflection h.bCalculated for nonglycine and nonproline residues using PROCHECK.括号内的数值对应最高分辨率壳层。aRsym = ∑ₕ∑ᵢ |Iₕᵢ − ⟨Iₕ⟩| / ∑ₕ∑ᵢ ⟨Iₕ⟩，其中Iₕᵢ为衍射指标h的第i次观测强度，⟨Iₕ⟩为衍射指标h所有观测强度的加权平均值。b 采用PROCHECK软件，针对非甘氨酸与非脯氨酸残基计算得到。
