Cytochrome and copper-binding domains in T2D RpNiR and comparison with the fully copper-loaded structure. (a) T2D RpNiR has no copper in the T2Cu site. Tyr323 has remained ligated to Asp97 and water and is in the locked position. 2Fo − Fc electron-density map is shown at 1.0σ (blue mesh). (b) Alignment of the T2D RpNiR structure (red) with the untreated wt RpNiR atomic resolution structure (blue; PDB entry 3ziy) showing close structural similarities, with Tyr323 in an identical position in T2D RpNiR despite the absence of T2Cu.
