Ation, or at the least a pointer towards how this ought to be accomplished. Authors’ response: We’re happy to view that Reviewer appreciated the scale of the trouble that the object of this study has set for theoretical calculations. We thank the reviewer for his pretty useful comments. We agreed and have taken into account all of them together with the single exception of the one that had been marked as an error by the Reviewer. We nonetheless believe that we’ve got utilized a suitable neo-Inositol supplier criterion for the salt bridges in our evaluation. Figure 1a and b, the necessity of which has been questioned by the Reviewer within the comment (34), show how our final model fits within the EM density. Inside the revised manuscript we provide some hints on how the functional consequences from our model could beShalaeva et al. Biology Direct (2015) 10:Web page 26 ofvalidated by mutating the acidic residues of Apaf-1. Of course, we hope to view a well-resolved crystal and or cryo-EM structure on the cytochrome cMB-0223 Formula Apaf-1 complicated in the close to future.Added filesAdditional file 1: Figures S1 and S2. Figure S1. Backbone coordinates RMSD heat maps for WD domains of Apaf-1 in complicated with cytochrome c for the duration of MD simulation. Figure S2. Conservation of negatively charged residues in the WD domains of Apaf-1 homologs. Further file 2: The PatchDock’ model structure right after power minimization. That is the structure obtained after manual editing of PatchDock-predicted model and energy minimization. The PatchDock’ model shows by far the most number of salt bridges involving functionally relevant cytochrome c residues and remained stable throughout molecular dynamics simulations.

Competing interests The authors declare that they’ve no competing interests. Authors’ contributions DNS performed molecular modeling and MD simulations, analyzed the data, at the same time as wrote the first draft with the manuscript, DVD performed the sequence analysis of cytochrome c, MYG performed the sequence analysis of Apaf-1 and contributed towards the writing the manuscript, AYM created the study, interpreted the data, and wrote the final version with the manuscript. All authors read, edited and authorized the final manuscript. Acknowledgements The authors are grateful to Prof. V.P. Skulachev for drawing their consideration for the prospective important function with the residues of Apaf-1 inside the formation of an apoptosome.
