Structural Analysis of Respirasomes in Electron Transfer Pathway of Acidithiobacillus ferrooxidans: A Computer-Aided Molecular Designing Study
Figure 4
(a) The spatial distribution of core hydrophobic residues (stick) that facilitate electron transfer to RcY protein. (b) Illustration of H-bonds (green dashed lines) formed between the residues of RcY-Cyc1 interacting complex. (c) The figure describes intermolecular contacts between the Cu center of RcY and the heme groups of Cyc1 through the His143-Glu121 interaction. (d) The figure depicts that the CO groups of heme A and heme B play crucial roles in their stability and electron transfer toward CoxB as revealed by strong intermolecular H-bond interactions (~2.5 Å).
