This blog are about articles in the field of Structural Bioinformatics that I found interesting and wanted to write a short description about them, so that others might find it interesting as well.

Resist Thy Temptations
by Ragothamanyennamalli in Getting to know Structural Bioinformatics
This is not a regular research blogging post, but important enough that anyone following this blog should be aware of it. Most of you doing research, I assume being associated with an institute/university, would have an academic email id that does not end with .com. You are vulnerable, my friend. Yes, the subject is "open access publishing scam".... Read more »

David Goodsell like images
by Ragothamanyennamalli in Getting to know Structural Bioinformatics
Almost all of us visiting PDB would have looked at the image shown below that attract us like moths attracted to a light. I am talking about the aesthetically pleasing protein images created by David Goodsell. In case you didn’t know, he is the author of Molecule of the Month series. Since the images look anything like the ones we usually keep looking at, one is attracted to the level of abstraction the image projects due to which, the reader understands the big picture. And, of course, th........ Read more »

Say Smiles
by Ragothamanyennamalli in Getting to know Structural Bioinformatics
Recently, Babel (in my system) was not working and I needed to convert my .sdf files to smiles format. I troubleshooted the error was able to run successfully. But, this made me think, what about a web-based application to do this format conversion? That's how I found these three amazing tools based at the National Cancer Institute's CADD Chemoinformatics group.... Read more »

What to do with so many models?
by Ragothamanyennamalli in Getting to know Structural Bioinformatics
I have encountered this issue while working with structures in PDB that are solved using Nuclear Magnetic Resonance (NMR). Which model should I choose among the 10 or 20 models? As a general rule of thumb, Model 1 is usually taken for further analysis and consideration. Is that rule universal for all NMR structures? Some studies on this topic makes it interesting to revisit.... Read more »

Quick and easy animated pictures of proteins
by Ragothamanyennamalli in Getting to know Structural Bioinformatics
So, here is an imaginary situation. You have a deadline to achieve and have minimal internet to reach the goal. Few hours before the deadline, your PI asks if you can send him a movie of the protein of interest in PyMOL. He specifies that the movie show the protein rotating, the active site and the ligand bound with it in surface representation, ligands as ball-and-stick, etc. He has a grant review presentation tomorrow and needs it asap.
You finish the movie and realize that to make a good i........ Read more »

Multiple Structure Alignment
by RagothamanYennamalli in Getting to know Structural Bioinformatics
Just like Multiple Sequence Alignment (MSA) tools there is a definite need for multiple structure alignment tools. For a long time, I was a big fan of Combinatorial Extension (CE)'s Multiple Structure Alignment (MStA) on their web server. Now, it is no longer maintained and has become a legacy. The good thing about it was you can do pairwise, database search, and MStA by either giving the PDB id or uploading a file.... Read more »

Molecular Dynamics and Pest Control
by RagothamanYennamalli in Getting to know Structural Bioinformatics
How can Molecular Dynamics help in controlling pests? Well, insects have something called resistant to dieldrin receptor or RDL receptors. These are part of a big family of receptors called Cys-loop receptors. Insecticides invariably bind to these receptors and in turn affect the neurotransmission in the pest. So, it becomes imperative to understand these receptors in order to develop and rationally design insecticides that are highly specific.... Read more »
