Synthetic biology: Building genetic containment

Author: Karmella A Haynes

Since the 1980s, scientists have worked on designing genetic codes to reinforce containment and control of genetically engineered microbes. New mechanistic studies of “deadman” and “passcode” gene circuits provide a flexible platform to build new safety switches.

Chemical probes: The many genes of drug mechanism

Author: Adam C Palmer

A small molecule's biological activity in a cell depends on the actions of many gene products. Correlations between basal gene expression and compound sensitivity across hundreds of human cell lines reveal a broad view of cellular mechanisms of action.

Protein aggregation: A rescue by chaperones

January 19th, 2016 by Joost Schymkowitz

Nature Chemical Biology 12, 58 (2016). doi:10.1038/nchembio.2006

Authors: Joost Schymkowitz & Frederic Rousseau

Protein aggregation is associated with more than 50 human pathologies, including prevalent conditions such as Alzheimer's and Parkinson's diseases. A phenotypic screen in Escherichia coli associating antibiotic resistance with the inhibition of protein aggregation now allows screening for chemical inhibitors of protein aggregation in a simple, fast and inexpensive manner.

Addicting diverse bacteria to a noncanonical amino acid

January 18th, 2016 by Drew S Tack

Nature Chemical Biology 12, 138 (2016). doi:10.1038/nchembio.2002

Authors: Drew S Tack, Jared W Ellefson, Ross Thyer, Bo Wang, Jimmy Gollihar, Matthew T Forster & Andrew D Ellington

Engineered orthogonal translation systems have greatly enabled the expansion of the genetic code using noncanonical amino acids (NCAAs). However, the impact of NCAAs on organismal evolution remains unclear, in part because it is difficult to force the adoption of new genetic codes in organisms. By reengineering TEM-1 β-lactamase to be dependent on a NCAA, we maintained bacterial NCAA dependence for hundreds of generations without escape.
