Re: [ccp4bb] Calculating over all bend in a DNA
Dear Sasha, you can select two pairs of three corresponding atoms at either end of the stand and calculate the plane normal of each set. The angle between the normals would be the overall bend.

Dear Sasha, dear all, I meant 'two _sets_ of three atoms each'. Thanks to Mark for pointing this out to me.

Re: [ccp4bb] Calculating over all bend in a DNA
Hi Sasha - you can use 3DNA: http://x3dna.org/; http://w3dna.rutgers.edu/ HTH, val On 21 October 2014 20:53, Sasha Pausch sashapau...@gmail.com wrote: Hello CCP4bb, May I know how can we calculate or use any server which can calculate the overall bend in a DNA (crystal structure)?
Re: [ccp4bb] Calculating over all bend in a DNA
Hi Sasha, You can also use Richard Lavery's webservice for Curves+ ( http://gbio-pbil.ibcp.fr/cgi/Curves_plus/ ) and visualize the curve of the helical axis in 3D in a molecular graphics program. In addition, you can do a normal vector analysis similar to the one suggested by Tim Gruene by running FREEHELIX by Richard Dickerson which has been available through the fink depository and which could be found this morning at the Nucleic Acid Databank via http://ndbserver.rutgers.edu/files/ftp/NDB/programs/freehelix98. Linux binaries and the source code are available. I was able to compile from source code on a Mac several years ago. Examples of our use of these programs as applied to two RNAs are found in PMID: 21878548.

Re: [ccp4bb] Calculating over all bend in a DNA
Hello CCP4bb, Based on suggestions from the members of CCP4bb, I used program Curves+ to check the bend (angle) in DNA. I have given my DNA which has two strands and 13 bases each as an input. I got an output file where I can see other parameters inferred from the structure. But I am getting a message at the end of the output file which I believe gives me answer for my question. (E) Groove parameters No groove analysis: Pabsent in strand = 1 at level = 11 Please indicate to me what could be the error in this? Thank you all for answers, On Wed, Oct 22, 2014 at 2:20 PM, Tim Gruene t...@shelx.uni-ac.gwdg.de wrote: Dear Sasha, you can select two pairs of three corresponding atoms at either end of the stand and calculate the plane normal of each set.
