Table 1. Data collection and structure refinement statistics of H. influenzae Hap_S.

^aBeamline designations refer to the Shanghai Synchrotron Radiation Facility, Shanghai, PR China.

^bR_sym=Σ(I−〈I〉)²/ΣI².

^cOverall, high-resolution shell in parentheses.

^dHigh-resolution shell: 2.225–2.200 Å.

^eR_free calculated using 5% of total reflections omitted from refinement.

^fR.m.s. deviations report root mean square deviations from ideal bond lengths/angles and of B-factors between bonded atoms (Engh and Huber, 1991).
