NewsScientists recode the genome for programmable synthetic proteins
Synthetic biologists were able to re-write the genetic code of an organism — a novel genomically recoded organism (GRO) with one stop codon — using a cellular platform that they developed enabling the production of new classes of synthetic proteins.

NewsNew study uncovers key differences in allosteric regulation of cAMP receptor proteins in bacteria
A new study provides key insights into how bacterial cAMP receptor proteins (CRPs) respond differently to the ubiquitous signaling molecule, cyclic AMP (cAMP), challenging the assumption that structural similarity predicts functional behavior in allosteric proteins.
