Hydrogen atoms were included in calculated positions, solvent molecules were added manually in COOT using 2|Fo|-|Fc| and |Fo|-|Fc| maps and occupancy factors were refined for disordered residues and the O2 molecules; anomalous dispersion parameters were refined for the selenium atom in Sec 489; anisotropic atomic displacement parameters were refined for all non-hydrogen and non-solvent atoms.
