All,
Is it possible to define restraints for individual amino acids in
refmac? For example, can I add planar peptide restraints to a small
region of my protein without applying those restraints to the entire model?
Thanks,
Sean

Hi Everyone,
I've been using programs ligplot and ligand explorer to view protein-ligand
and protein-cofactor interactions of a structure I've recently solved. Can
anyone suggest a better program to view these interactions? Ligand explorer
seems to only show distance (and not geometric) dependent
Hi all
One should be aware of some stats about twinning (and in general):
1) If you have perfect hemihedral twinning and no correlated
rotational NCS then random R factors are around 40 instead of
Luzzati's 58.
2) If you have perfecthemihedral twinning and you are not modelling
twin then r

Twinning has two effects:
The effective ration of observations/variables decreases with
increasing twinning fraction.

I don't know how REFMAC5 handles twinning, but if the structure is
simply split into two identical parts, eac

Hi all,
kind of a weird problem - the R-factors of a refinement using the new
twin refinement in refmac are low, almost suspiciously low:
A good 1.9AA data set, space group H3/R3, many statistics starting
with truncate's cumulative intensity distribution clearly suggest
