Good morning ccp4bb-ers! I have two protein-protein complex structures, and the orientation of one of the components shifts slightly with respect to the other component between the two structures.
If I run superimpose on the shifting component I get this: CROWTHER ALPHA BETA GAMMA 12.41607 -9.09294 -9.64895 SPHERICAL POLARS OMEGA PHI CHI 73.10930 -78.96756 9.50379 DIRECTION COSINES OF ROTATION AXIS 0.18311 -0.93918 0.29055 Angle between rotation axis and Centroid vector 93.14726 ***** Note: Since this angle between rotation axis and Centroid vector is near to 90.0 this may represent a pure rotation *** This is fine - Its what I expected. However. I would like to know how I can graphically represent this axis in Coot/Pymol/CCP4MG? This has probably been asked before, but a quick google of the archives reveals nowt. Can anybody help?
