I added a new page called Q&A.  Use this section if you have a question that is not about one of the blog posts.   Please contribute to answer too.

I read an interesting Shewanella paper on a solution structure of MtrA.  I was really excited when I first saw the paper.  But the paper leaves more question than answers.  The structure they show in Figure 5 is not really a structure.  It looks like a tounge 40 x 30 angstroms in size.  It would be nice if they report a pdb file but I don’t think they were able to generate one based on the techniques.  Hopefully a crystal structure will be done someday.  Here is a link to the paper:
