Genomically recoded organisms: redefining and safeguarding biological systems

In a recent report, Grome et al. describe a genomically recoded Escherichia coli strain with a 62-codon genome and a single stop codon. This and other genomically recoded organisms (GROs), engineered with modified genetic vocabularies, enable the creation of novel proteins and biomaterials, while ensuring the safety and viability of GRO-based biomanufacturing.
