Dear All,
Recently I collected a data set to about 3.1 angstrom. Using Xtriage program, I
found a pseudo translational symmetry on the c-axis. I noticed that overall
diffraction intensity is weak for this dataset. I wonder if there are flaws in
the crystal and I have difficulty to solve the
Dear All,
I have a question regarding solving a crystal structure by molecular
replacement. It is a single protein with a molecular weight of 25.5 kDa. The
cell dimension is rather big from the diffraction data ( 90.9 Å, 143.9 Å,
216.3Å, 90°, 90°, 90°). The possible space group is P212121.
Dear All,
I have a question regarding refinement of a crystal structure with
intermolecular disulfide bond. There is one monomer in an asymmetric unit. The
biological assembly for the molecule is a disulfide bond linked dimer. And the
disulfide bond is on a 2-fold crystallographic symmetry.
Dear All,
I have a question regarding making disulfide bonds in Pymol. The overall
structure is in cartoon representation. When I display the disulfide bond
residues as stick models, the cysteine residues sitting on the beta strand have
a gap from the actual beta-strand. If I check off the
