Hello everyone,
I have two pdb files for molecule A (A.pdb and A_polyala.pdb) from
which I would like to make a hybrid file A_semi.pdb. A_semi.pdb will
have some residues with full sidechains (so derived from A.pdb) and
some residues with only a C-beta atom for a sidechain (so derived
from A_polyala.pdb). The residues I would like mutated are listed in
file B.txt (in total about 250 residues to be mutated). I could do
this by hand but I figure there must be a fater way to do it. Does
anyone have any suggestions on how I might be able to do this? Is
there some unix search-and-replace command line I could use to
replace all lines of text in A.pdb containing ### (spaced
appropriately) with those lines of text in A_polyala.pdb containing
the same ###, and then have it repeat this for all ~250 residues
listed in the file B.txt?
Many thanks in advance,
Shekeb
You can assign a sequence to a pdb file in Xfit for example, but it will
replace the sidechain only with the top rotamer, so you will have to
walk through your chain and actually fit it to your density.
If I remeber it correctly also arp/wARP has such a feature to assign a
sequence to a pdb file.
You can also run Molrep and assign a sequence and then stop molrep and
take the assigned.pdb file.
Not sure if Coot 0.3.1 sports this feature now, it was always planned,
but not sure if ever implemented.
