^a Beamline 5C at Pohang Acceleratory Laboratory (PAL) in the Republic of Korea.

^b Values in parentheses are for the highest resolution shell.

^c R_merge = ∑_h = _i |I(h)_i- < I(h) > |/ [∑_h /_iI(h)_i], where I(h) is the intensity of reflection of h, ∑_h is the sum over all reflections and -_i is the sum over i measurements of reflection h.

^d CC_1/2 was calculated from HKL2000.

^e R_work = Σ_hkl ||F_o|–|F_c||/(Σ_hkl|F_o|); 5% of the reflections were excluded for the R_free calculation.
