Data processing and refinement statistics.

aValues in parentheses apply to the high-resolution shell.
b; Nh, multiplicity for each reflection; Ii, the intensity of the ith observation of reflection h; , the mean of the intensity of all observations of reflection h, with ; is taken over all reflections; is taken over all observations of each reflection.
c; ; Rcryst and Rfree were calculated using the working and test hkl reflection sets, respectively.
dTotal refined protein residues equal 3172, from which 28 terminal amino acids (the N- and C-termini on the 9 chains; plus residues: TS#399, TS#409 (in chains A, B & C), Fab#27, Fab#29 (in chain H), Fab#137, Fab#139 (in chain I), all flanking unmodeled gaps) were not included in the Ramachandran analysis (as implemented in Coot v 0.6.2-pre-1).
