An Excellent Review of Protein Docking

As a result of work we are doing over on ChemSpider regarding LASSO I have become increasingly interest in the world of protein docking.  A great review article was just released. I highly recommend it if this is an area of interest for you.

Protein-ligand Docking: A Review of Recent Advances and Future Perspectives

Understanding the interactions between proteins and ligands is crucial for the pharmaceutical and functional food industries. The experimental structures of these protein/ligand complexes are usually obtained, under highly expert control, by time-consuming techniques such as X-ray crystallography or NMR. These techniques are therefore not suitable for routinely screening the possible interaction between one receptor and thousands of ligands. To overcome this limitation, computational algorithms (i.e. docking algorithms) have been developed that use the individual structures of the receptor and ligand to predict the structure of their complex. The present review, then, summarizes: (a) the fundamentals of the algorithms of the most commontly used docking programmes (with particular emphasis on their strengths and limitations); (b) how the results from different docking algorithms compare (i.e. which software gives the best predictions); and (c) the future perspectives and challenges for docking techniques.

The Full NMR Assignment of Hexacyclinol using CASE now published

The hexacyclinol debacle has been highlighted on a number of blogs and has caused a furor within the organic chemistry community. I have discussed this previously on the ChemSpider blog. Well, I am happy to say that the article describing our work is finally available as an ASAP article online . This was certainly an interesting piece of work to be involved with, was a detective story from start to finish and brought together a very skilled team to work on this issue. In my opinion this study truly shows the capabilities of Computer-Assisted Structure Elucidation.
