PONE-D-23-36013Sequence, Structure, and Epitope Analysis of the Polymorphic Membrane Protein Family in Chlamydia trachomatisPLOS ONE Dear Dr. D'haeseleer, Thank you for submitting your manuscript to Traffic. Your study has been sent to two referees for evaluation, and their reports are enclosed below. As you can see, while both referees consider the findings interesting, they also raise important points that need to be addressed before they can support publication in PLoS One. The paper by Debrine et al (doi: 10.1128/spectrum.03242-23), that was published before you submitted your MS, needs to be acknowledged. It will be useful for readers to state clearly in the discussion whether your conclusions differ or not, considering that the same prediction tools have been used. Also, as stated by reviewer 2, it is expected in the discussion (or in the results section, if helps keeping the flow) that you validate (or not) some of your structural predictions based on published functional work. Please submit your revised manuscript by Jan 25 2024 11:59PM. If you will need more time than this to complete your revisions, please reply to this message or contact the journal office at plosone@plos.org. When you're ready to submit your revision, log on to https://www.editorialmanager.com/pone/ and select the 'Submissions Needing Revision' folder to locate your manuscript file.

(Please upload your review as an attachment if it exceeds 20,000 characters) Reviewer #1: The manuscript by Cervantes et al provides an excellent description of in-silico-based analysis of the chlamydial Pmp family of proteins. The depth of analysis is considerable and the paper is well written. I have no significant criticisms of the work. The molecular dynamics, epitope prediction, and hinge analysis are particularly unique. A similar paper has recently been published that describes an Alphafold-based analysis of this family of proteins. This manuscript and that paper look at the same issue from slightly different perspectives and both will be useful to the research community. It is suggested that these authors cite the other manuscript and perhaps briefly describe differences between the documents, with a goal of helping researchers get a wider perspective on predicted Pmp structure. There are data in that manuscript that differ slightly from this one, and certain subjects are addressed by one and not the other one. Both documents will be valuable to people who wish to explore chlamydial Pmp structure. Minor comments about the writing: Lines 183 vs. 185, and elsewhere… the designation of I,L,V or ILV needs to be consistent. Perhaps the MOMP presentation in the Introduction is too drawn out. Lines 32-43 could probably be condensed to one or two sentences. Lines 80-83: A distinction between the sequence similarity in the beta barrel vs the beta helical domain, across the Pmp proteins, might be useful here. Reviewer #2: Review of MS PONE-D-23-36013 by Cervantes et al. This MS utilizes protein structure prediction algorithms to visualize, for the first time, the Pmp family from C. trachomatis Serovar E. A special focus has been put onto the tetrapeptide motifs, GGA(I,L,V) and FxxN. The MS is interesting and adds to our understanding of Pmp protein function. My main critics is that the authors do not try to compare their Pmp structures with published functional data on Pmp proteins and protein fragments. We have published for C. pneumoniae Pmp21, that different protein fragments have different adhesion capacities and that protein fragments with 2 motifs, when point-mutated, lose this capacity (Mölleken et al ). Our study on C. trachomatis Pmps shows that certain motif-rich and motif-poor Pmp protein fragments have a different capacity for adhesion and oligomerization (Favaroni 2021). Finally, we have used large segments of certain C. trachomatis Pmp proteins for a vaccine study (Lanfermann et al; doi.org/10.3390/vaccines9060609). Finally, our biochemical work on a Pmp21 protein fragment has revealed that this protein domain forms oligomers that adopt an amyloid-like structure comparable in size and shape to protofibrils of the amyloid protein Abeta42 (Luczak et al). It would be really interesting to compare the detailed structures presented in this MS with some of the functional data published. The introduction is detailed but needs a few corrections: Line 47: “….viable vaccine candidates…”. The authors missed one recent publication which convincingly shows that a mix of different recombinant C. trachomatis Pmps induces a high degree of cross-serovar protection against urogenital and ocular strains of C. trachomatis: Lanfermann et al., DOI: 10.3390/vaccines9060609. Line 56: “Pmps are autotransporters”. That is not true. Pmps are predicted to be autotransporters. So far no experimental prove. Needs to be corrected. Fig. 6 shows a molecular dynamics simulation of PmpE with the β-barrel domain embedded in a POPC bilayer. I am wondering whether the simulation gives a similar result, when the authors take into account that a typical outer membrane of a G- - negative bacterium is very asymmetrical, with phospholipids in the inner leaflet and LPS in the outer leaflet, plus all of the transmembrane proteins with their β-barrel fold (outer membrane proteins (OMPs)) and the lipoproteins. Fig. 7. I could not find a figure legend. Line 359. The authors define proline-rich regions (PRRs) as having at least a P-X0-2-P motive (see Fig. 9 legend). What is the basis of this definition? Fig. 9. The legend says: “…A few proline-rich regions in side loops of PmpC, PmpG, PmpH and PmpI are labeled.” . To make this point stronger, the authors should label all proline-rich regions - not only a few. Johannes Hegemann ********** 6.

(Please upload your review as an attachment if it exceeds 20,000 characters) Reviewer #2: Review of MS PONE-D-23-36013_R1 by Cervantes et al. In the revised MS, the authors dealt satisfactorily with all the points I had raised. In particular, I like the data and the discussion about the oligomerization potential of Pmp proteins. One important aspect I did not mention in my first review concerns the terminology: The authors use a structure prediction program as a basis for their work. Therefore, all conclusions from these structural predictions are also predictions and not experimentally documented facts. This should be clearly indicated throughout the MS, e.g. - the title of this MS omits this fact, - Line 11. Under ´Keywords` no mentioning of the use of a structure prediction program…. - in the second line of the abstract (lines 15-16) the authors state “Here we show that the 16 characteristic GGA(I,L,V) and FxxN tetrapeptide repeats fit into a larger repeat sequence….” . Up to here, no mentioning of a structure prediction program. I suggest starting the abstract with sentence # three of the current abstract (Analysis of the protein using structure prediction algorithms provided novel insight to the chlamydial Pmp family of proteins.). - line 23. The authors state `This structural analysis….` . It is a predicted structure… Minor points: - Line 54. The Greek symbol for beta is missing. - Figures 1+2. Some of the text in the figures are not readable….. Johannes Hegemann ********** 7. PLOS authors have the option to publish the peer review history of their article (what does this mean?).
