[ccp4bb] adding H to DNA

2012-12-26 Thread cuisheng2007
Dear all:

I encountered problem in adding hydrogen to my model including protein and
DNA components using phenix.ready_set or phenix.reduce. Hydrogens are only
added to protein but not to DNA.

Any ideas of fixing the problem?

 

Many thanks and best regards

[ccp4bb] diagram of dsDNA

2012-09-05 Thread cuisheng2007
Dear all

When I was playing around with Nucplot to generate diagram for dsDNA/Protein
complex, the base pairs are displayed as letters. There must be a way of
showing the bases as squares, a better illustration, but I cannot find a way
of changing it in the nucplot.par. Does anyone know how to deal with it?

 

Many thanks!

[ccp4bb] DNA geometry

2012-08-28 Thread cuisheng2007
Dear all:

Is there software or web-server that can measure DNA geometry (PDB
coordinates) precisely, such as groove width, helix diameter, helix axis,
base tilt angle, helix rise per base pair.

It is surely doable to measure and estimate them manually, but I am just
wondering if there are better ways or automatic ways. 

Many thanks
