The individual boxes you circled in purple refer to different ribosomal proteins. Map map03010 is thwe reference map containing information on all organism. The vertical shift of the boxes shows whether an ortholog of this particular protein is found in bacteria only(B), bacteria an archea (B/A), Archea and Eukaryotes(A/E) or Eukaryotes only(E), as denoted by the boxes circled in red. The color of these boxes is the color of the set of these proteins in the schematic representation on the left.

Dear Prof,

Thank you very much.

1- How can we find out the names of these proteins e.g. S10, L3, L23 etc. ?

2- How can we differentiate between proteins with up or downregulated expression?

1 - S10, L3, L23 are the names of the proteins. If you click on any of the purple boxes, you get more details about the corresponding protein, including synonymous names.

For example, S17 is protein 17 of the small ribosomal subunit, synonymous names are: RP-S17, MRPS17, rpsQ

1 - by experimentally comparing the expression levels without and with the treatment of interest. To determine the transcription levels (amount of mRNA) for the genes coding for these proteins, you can use rt-qPCR

Annemarie Honegger Thanks for your prompt response. Actually, I had ribosome KEGG pathway in a JPG.file format, where I was unable to decode the information. But, now I've browsed (https://www.kegg.jp/kegg-bin/show_pathway?lpb03010), and got some details e.g. /enzyme/protein codes and names etc.
