Table 1. X-ray data-collection statistics.

Values in parentheses are for the highest resolution shell.

Space group	I23
Resolution (Å)	40.07–2.98 (3.14–2.98)
Unit-cell parameters (Å, °)	a = 98.16, α = β = γ = 90.00
Total reflections	18394 (2571)
Unique reflections	3337 (490)
Completeness (%)	99.7 (99.6)
Rmerge†	0.096 (0.474)
〈I/σ(I)〉	11.2 (3.5)

^† R _merge = , where I _i(hkl) is the intensity of the ith observation of reflection hkl and 〈I(hkl)〉 is the average intensity over symmetry-related observations of reflection hkl.
