Organic Division North-West Regional Meeting 2019

23 May 2019 10:00-17:30, Lancaster, United Kingdom

The meeting will feature speakers from regional universities and chemical industry, and will conclude with the presentation of the RSC Bioorganic Award to Prof Floyd Romesberg (Scripps Research Institute), who will deliver a lecture entitled 'A Semi-synthetic organism that stores and retrieves increased genetic information' (abstract below). The event will also feature exhibitions, a delegate poster session, lunch and drinks reception. Please join us in Lancaster for a vibrant celebration of organic chemistry in the North West. 

A Semi-synthetic organism that stores and retrieves increased genetic information

Since the last common ancestor of all life on earth, the biological diversity has been encoded in a four letter, two base pair genetic alphabet. Expansion of the genetic alphabet to include a fifth and sixth letter than for a third, unnatural base pair not only has immediate utility for a number of applications, such as site-specific oligonucleotide labeling, but also serves as the foundation for an organism with an expanded genetic code. Toward this goal, we have examined a large number of different unnatural nucleotides bearing mainly hydrophobic nucleobase analogs that pair based on packing and hydrophobic interactions rather than H-bonding. Optimization based on extensive structure-activity relationship studies and two screens resulted in the identification of a class of unnatural base pairs that are well recognized by DNA and RNA polymerases. More recently, we have engineered E. coli to import the requisite unnatural triphosphates and shown that DNA containing the unnatural base pair is efficiently replicated, transcribed, and translated within the cell, resulting in the first semi-synthetic organism that stores and retreives increased information.
