shape complementarity between protein and DNA surface


From: Deepak Thankappan Nair

Dear All
For calculation of the shape complementarity index using the Sc
program between a protein and DNA surface, does anybody have a
modified radii.lib file that includes information about DNA atoms?
Also, is there any reference that has information regarding the atomic
radii of DNA atoms?
thanks
Deepak

Dear Deepak,

the only atom type present in DNA and not in Proteins would be the
Phosphorus. You can probably add this to sc_radii.lib yourself with the line
***    P*      1.80

the radius stems from http://en.wikipedia.org/wiki/Phosphorus and the
link to http://en.wikipedia.org/wiki/Van_der_Waals_radius provides you
with the reference.

The results will hardly differ if you modify this value within 100%, I
guess.

Cheers,
Tim
