Figure 9. Hemes of DA-Cld and DyP.
(A) Stereo view comparing heme orientation in DA-Cld and DyP. (B) Interactions of the propionates of DA-Cld. (C) Interactions of the propionates of DyP. Active site residues and hemes are shown as sticks and colored by atom with DA-Cld (carbon green) and DyP (carbon orange). Regions associated with DyP are labeled in orange font. Pyrrole rings of the heme b cofactor are labeled and shown in bolded font. The hemes in DA-Cld and Dyp are related by a 180° flip along an axis through pyrrole positions D and B.
