Protein contact maps are symmetrical and look great, but how does one read one?
I tried to underside the following source: 'Understanding contact patterns of protein structures from protein contact map and investigation of unique patterns in the globin‐like folded domains' Journal of Cellular Biochemistry (Pay-wall) .. but it has proven to be difficult to understand.
For illustrations, subfigure 1.A is an example of a 'Protein Contact Map':
Could someone explain or are there other useful texts I could use?
