Ation, or a minimum of a pointer towards how this ought to be completed. Authors’ response: We’re content to find out that Reviewer appreciated the scale of your issue that the object of this study has set for theoretical calculations. We thank the reviewer for his very valuable comments. We agreed and have taken into account all of them using the single exception on the one particular that had been marked as an error by the Reviewer. We nonetheless think that we’ve got applied a appropriate criterion for the salt bridges in our evaluation. Figure 1a and b, the necessity of which has been questioned by the Reviewer in the comment (34), show how our final model fits in the EM density. Inside the revised manuscript we give some hints on how the functional consequences from our model might beShalaeva et al. Biology Direct (2015) ten:Page 26 ofvalidated by mutating the acidic residues of Apaf-1. Naturally, we hope to see a Alopecia jak stat Inhibitors targets well-resolved crystal and or cryo-EM structure in the cytochrome cApaf-1 complicated within the close to future.Further 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 in the course of MD simulation. Figure S2. Conservation of negatively charged residues in the WD domains of Apaf-1 homologs. Added file two: The PatchDock’ model structure after power minimization. This is the structure obtained right after manual editing of PatchDock-predicted model and power minimization. The PatchDock’ model shows by far the most variety of salt bridges involving functionally relevant cytochrome c residues and remained stable in the course of 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, too as wrote the first draft of the manuscript, DVD performed the sequence evaluation of cytochrome c, MYG performed the sequence evaluation of Apaf-1 and contributed for the writing the manuscript, AYM made the study, interpreted the information, and wrote the final version of your manuscript. All authors read, edited and authorized the final manuscript. Acknowledgements The authors are grateful to Prof. V.P. Skulachev for drawing their focus towards the possible key role in the residues of Apaf-1 inside the formation of an apoptosome.
