Building DNA along A PBD Using RNA command
by Joshua Carter 23 Sep '13

23 Sep '13

Hi, I'm working on a project in chimera that involves modeling the binding of a RNA-guided protein complex to a double stranded piece of DNA. What I need to do is be able to is either match a DNA pdb to the existing RNA pdb I have or build one using the rna command in chimera. I know there is a path command, is there any way I could specify that to build along a pdb I have already? Or am I just barking up the wrong tree entirely? Thanks,Josh

Hello
by A Amiri 19 Sep '13

19 Sep '13

Hello. I have a problem with chimera! i want to join two pdb file together by C-N peptide bond. Actually this is a modeling of a fusion protein that one part of its, is a protein and another part is a linker. I need a complete structure. I select the carbon atom from one model and nitrogen atom from another model. I use the "build structure<join modesl" menu for this purpose but the "apply" button is inactive still and i don't know how i can activate it! … [View More]

Re: [Chimera-users] vop cover
by Elaine Meng 18 Sep '13

Hi Pradeep, That message is saying you must specify the density map. I.e. if the atomic structure is model #0 and the density map is model #1, the command could be something like vop cover #1 atom #0 Command usage and options: <http://www.rbvi.ucsf.edu/chimera/docs/UsersGuide/midas/vop.html#cover> Elaine ----- Elaine C.

Problem Using Transparency Command in Chimera
by Joshua Carter 18 Sep '13

18 Sep '13

Hi, My name is Josh Carter and I am an undergraduate researcher working at Montana State University. I am using chimera to make a movie a a protein complex interaction and I'm having trouble with the transparency command. When I type in just the command into chimera it doesn't even recognize it as a command. surftransp works but transp or transparency aren't recognized. Is there a bug fix I can run for this? Thanks,Josh

How to determine the distance from SG of Cys to the centroid of a nearby Trp ring
by Pande, Ajay K 17 Sep '13

17 Sep '13

I am using Tools/Structure Analysis/Axes -Planes-Centroids. Selecting the Trp Indole ring, obtaining the centroid. Then selecting SG of Cys and the centroid and drawing an axis. That axis does not seem to pass (exactly) through the SG and Centroid- that' my first problem, the 2nd problem is to get the distance between the centroid and SG.

colour by attributes is only colouring one chain of the dimer, how to make the colouring apply to both chains of homodimer
by Anne-Frances Miller 17 Sep '13

17 Sep '13

Dear team Chimers 1- Thank you for GREAT software ! 2- How to make the colouring apply to both chains of homodimer ? I have a homodimer in which features of the active site derive from both monomers so the degree of active site conservation will only show up if I can apply colour by attributes to both monomers (attribute will be conservation) Right now, colour by attributes is only colouring one chain of the dimer, chain A.

Chimera Questions
by Serina Doolittle 16 Sep '13

16 Sep '13

Hi, My name is Serina Doolittle. I am an undergraduate research student at Armstrong Atlantic State University in Savannah, Ga. I am currently using Chimera to build two protein models. I have the proteins in the form that I want them in to 3D print. However, one of them is not a single chain protein. It has chain A and B. I hid chain B and focused on chain A because of the simplicity for the 3D protein model that I want. However, when you hide chain B and you put chain A on "show surface" … [View More]

How to move a domain in mouse mode /move selection
by Juergen Joachim Mueller 12 Sep '13

12 Sep '13

Hallo, how can I move a domain consisting of 3 chains using mouse mode/ move selection? I will use chain A: 6-121, chainB: 7-103, Chain C: 6-103. The selection by command line takes always the longest number 121 for all three chains - A:6-121, B:7-121, C:6-121. Greetings, Jürgen (Chimera production version 1.8 (build 38824) Windows8)
