Re: [ccp4bb] one metalloid making multiple covalent bonds - generating library

2017-03-10 Thread Robbie Joosten
Hi Thiyaga, Rather than compounds, you should define LINKs. You can do this in the CCP4 program jligand. You may also want to define angle restraints depending on your resolution. In Refmac you can do that as external restraints. A similar situation is described in this (http://journals.iucr.o

[ccp4bb] one metalloid making multiple covalent bonds - generating library

2017-03-10 Thread S. Thiyagarajan
Dear Experts,I have a metalloid complex in a structure I am solving, where a single ion makes 3 covalent bonds to 3 different cysteine residues, at a bond length of 1.8 A. How to generate the monomer library for refinement? Leaving it without the bonds makes the SG atoms go farther than the requi

Re: [ccp4bb] Fwd: how to calculate a difference map between two heterodimers in heterotetrameric protein

2017-03-10 Thread Phil Jeffrey
Tricky - perhaps this could be viewed as "anti-averaging" methodologically. Use USF programs MAMA, IMP to generate a mask and optimize the NCS operator (or skip this step if you feel you know yours accurately) Use CCP4's MAPROT to rotate the map of one monomer onto the other Conceivably use U

2017-03-10 Thread Eleanor Dodson
This would be pretty difficult, but you know in COOT you can overlap the maps for related chains / hetero dimers/ etc. ( Ask for NCS difference maps in the DRAW menu ] The matrix which converts one set of coordinates to the other is then applied to the electron density so you see the NCS relatd ma

Dear All, We are working on a tetrameric protein containing 2 heterodimers which are related to each other by 2 fold symmetry. There are difference at the active site between the two heterodimers in the crystals, and we would like to make a difference map to compare one heterodimer to the other.
