Biochemistry of Copper Site Assembly in Heme-Copper Oxidases: A Theme with Variations
Round 1
Reviewer 1 Report
The manuscript depicts de state-of-the-art of Cytochrome c Oxidase
assembly, emphasizing the available mechanisms for copper sites
assembly. I've found this paper is a chomprehensive, although extensive
review of biological mechanisms underlying the assembly of
copper sites in COX.
Particularly , I found the discussion about the role of metallochaperone module essential in unvealing the sequetial steps for CuA assemby as illustrated in Fig. 3, and the structural details of relevant proteins in the metallochaperone module (Fig. 4) because in this manner both mechanistical/structural insights become more accesible to a larger audience. Moreover, I consider the introduction of short section briefly describing CuA assembly process in mitochodria very useful, coupled with the strategy for the biochemical analysis of mitochondrial metallochaperone module. As a minor comment I would suggest the authors to shorten the lenght of the conclusion section and to present the main chalenges regarding the assembly pf COX in different organisms in a more focussed manner.
Author Response
We thank very much the reviewer for the positive comments on our work. We have shortened the conclusions section, and reorganized the main challenges with the aim of making them more clear and easy to read. Also, We have taken care of some grammar and typos throughout the manuscript.
Reviewer 2 Report
This work aim is to review ultrasensitive new Biochemistry of copper site assembly in heme-copper 2 oxidases: A theme with variations
This review is essential for aerobic respiration and general educational in the field.
They summarize the more common and applicable assembly of COX, with special emphasis in the assembly of copper sites.
