Synthetic biology enables the engineering of proteins with unprecedented properties using the co-translational insertion of non-canonical amino acids. Here, we presented how a spectrally red-shifted variant of a GFP-type fluorophore with novel fluorescence spectroscopic properties, termed "gold" fluorescent protein (GdFP), is produced in E. coli via selective pressure incorporation (SPI).
