Abstract
En 中文
For over a billion years, the central dogma of biology has been limited largely to 20 canonical amino acids with relatively simple functionalities. The ability to rationally add new building blocks to the genetic code has enabled the site-specific incorporation of hundreds of noncanonical amino acids (ncAAs) with novel properties into proteins in living organisms. Recent technological advances have enabled high level mammalian expression of proteins containing ncAAs, the use of unique codons to direct ncAA incorporation, extension of this methodology to a range of eukaryotic organisms, and the ability to encode building blocks beyond a-amino acids. These ncAAs have been used to study and control proteins in their native cellular context and to engineer enzymes and biotherapeutics with improved or novel properties. Herein we discuss recent developments in the field and potential future research directions.
