You know about adenine, thymine, guanine, cytosine. Now get used to SICS and MMO2.
In this JACS article published this month, researchers at the Scripps Institute reported the identification of these two artificial bases. They are efficiently incorporated during in vivo DNA synthesis by the Klenow fragment of E.coli DNA polymerase and pair together with high fidelity.
At the moment the applications for these new bases are are limited mainly to providing new building blocks for the in vivo synthesis of DNA-based nanostructures. However, work is ongoing to incorporate them into living cells and make them code for specific amino acids. Although it is far from clear whether this can be done, if achieved it will lead to some new, very powerful tools for protein engineering.
One of the really exciting parts of being involved in research is the opportunity to travel to a conference (hopefully at an exotic location!) to present your work and get to see presentations from the major players in your chosen field. Now you’ll probably have all sorts of frivolous reasons for not wanting to go […]
