Structure around the axial ligands. (a) A 2Fo − Fc map around His68 is shown as a grey mesh contoured at the 2.0σ level in the oxidized form 1 structure. Dashed lines indicate hydrogen bonds between His68 Nδ1 and Phe63 O and between Ser69 and the 7-propionate. (b) A 2Fo − Fc map around His44 is shown as a grey mesh contoured at the 2.0σ level in the oxidized form 1 structure. The dashed line indicates the hydrogen bond between His44 Nδ1 and Gly47 O.
