sfGFP with Amber outside the chrom.
Group: Freiburg
Author: Alisa
Summary: Superfolder GFP is an improved variant of the original Green Fluorescent Protein and is used as a fluorescent reporter Protein. By mutating position 66 to an amber stop codon, the incorporation of a noncanonical amino acid instead of Tyrosine in the chromophore is made possible. .

Usage
sfGFP is a widely used fluorescent reporter protein [1]. It is used to study protein expression and dynamics in living cells. Superfolder GFP is a faster-folding variant of the original Green Fluorescent Protein. Fluorescence can be observed when exciting the chromophore of the protein with a laser and detecting the emitted fluorescence. By mutating a Phenylalanine at a permissive site to an amber stop codon, the incorporation of noncanonical amino acids can ne studied. The Biobrick is especially useful as a control for noncanonical incorporation into the chromophore. [2]
Biology
GFP was first extracted from the Aequorea victoria, where it is responsible for Bioluminescence. [3]
Characterization
Without an orthogonal translational machienery able to incorporate noncanonical amino acids, only truncated, unfunctional proteins should be translated, and no fluorescence should be visible.
