Dear all,
I have a question regarding real-space refinement of Xylotetrose in
coot.
Xylotetrose is the 4-mer of D-Xylose (XYS in the monomer library of
coot).
I have set-up Xylotetrose as a polymer consisting of 4 attached
monomers linked by
oxygen called O4 (monomer 3002) between carbon C1 (monomer 3001) and
carbon C4 (monomer 3002) and
so forth.
However the program does not recognise the link between the rings and
instead of refining a polymer it
refines 4 separate D-xylose rings. It does not help to push the rings
closer, regularisation pulls them apart.
Any suggestions?
Best Regards,
Maria Håkansson
