DNA and Protein - Quite a Match!

JB

I thought I should alert readers to this essay by Mike Gene about the makeup and interaction of proteins and DNA.  From the essay:

Thus, as a consequence of amino acid structure, proteins will not only form folded structures using the same rules that form the double helix of DNA, , but they will form a cylindrical structure whose appendage (side chains) seem to be well-matched for scanning and binding to the winding major groove along the double helix. That is, the pattern of outreaching side chains can reach into the major groove and interact with the pattern of base-pairs inside the wide crevice of the major groove. But how well matched is the alpha helix and major groove?.... [quoting another source] "the structural coincidence of the alpha helix diameter of 12Å being the same as the width of the major groove in B-form DNA".  Why think it is merely a coincidence that the alpha helix diameter and the width of the major groove are the same? On the contrary, it simply enhances and extends the inherent rationality and complementarity that lies behind these two crucial biological molecules
