Hi everybody, I just crystallized a new project protein. How can I find a possible model for using molecular replacement? I have the sequence of my protein. Is it enough to make a …

I'm aware of GPU computing making great strides in tomography, but are there any projects which use GPGPUs in structural biology? Or, are the algorithms from, for example, crystal …

Hi everybody, I just asked myself what kinds of analysis is possible for a protein structure.I know that there are so many programms and software for almost any type of question a …

Can anybody recommend a program to plot a couple of amino acid residues of a active site/cavity in 2D? A screenshot of the active site is to confusing. Thanks, P. edit: As far as …

Does anybody remember a publication, where the authors tested the least needed homology for molecular replacement? I think they created a protein with homology around 20% which was …

I want to know how I can calculate the alpha helical radii in a 3-D structure of a protein. Is there any programme to calculate the radii of alpha helices?

Is there a server to quickly check, given an antibody structure, if the CDRs are in the canonical structural classes (except for the H3). I've already looked here (http://www.bioin …

In proteins (and RNA), the term "rotamer" is used to refer to a specific conformer (or class of conformers), found in structures. According to IUPAC (http://goldbook.iupac.org/R054 …
