Dear Chimera-users,
I would often like to take a pdb of a protein-DNA complex and just change one aa or one base pair. Can Chimera do this? If not, does anyone know of free software that can (for example, Swiss-PDB Viewer can mutate an aa, but not a base).
Two chimera commands do this: 'swapaa' and 'swapna' - which take as a first argument the amino acid or nucleic acid three letter code, and as a second the range of residues that are to be substituted. For example : swapaa ala :1-15 (the command line is opened via the favourites menu) enjoy! Jim Procter -- ------------------------------------------------------------------- J. B.
