Scientists at The Scripps Research Institute (TSRI) report in an upcoming article in the Journal of the American Chemical Society their synthesis of a form of the bacterium Escherichia coli with a ...

Synthetic bacteria with expanded genetic codes can evolve proteins in the laboratory with enhanced properties using mechanisms that might not be possible with nature's 20 amino acid building blocks.

Crack open a biology textbook and you will find a standard icon of molecular biology: the table summarizing the standard genetic code. This refers to the set of rules by which the cell "decodes" the ...

A team of investigators at The Scripps Research Institute and its Skaggs Institute for Chemical Biology in La Jolla, California has modified a form of the bacterium Escherichia coli to use a 22-amino ...

There are 20 canonical amino acids that are encoded by the genetic code of nearly all known organisms - there are only very few exceptions. In order to add novel building blocks to this existing ...

A surprising number of microbes use alternate genetic codes, different from the standard genetic code that governs the large majority of life. A census of these "recoded" genomes was recently reported ...

Evolution settled on a genetic code that uses four letters to name 20 amino acids. Synthetic biologists adding new bases to DNA will be free to improve on nature — if they can. With recent innovations ...

The dictionary of life has a new update. A DNA sequence that signals cells in almost all other organisms to stop synthesising proteins instead encodes a rare amino acid in some archaea, according to a ...

LA JOLLA, CA - In recent years, scientists have engineered bacteria with expanded genetic codes that produce proteins made from a wider range of molecular building blocks, opening up a promising front ...

Research suggests that we may have only begun to scratch the surface on the number of variations present in the genetic codes of all living organisms. Crack open a biology textbook and you will find a ...
