superfolder GFP coding sequence
| Types | DnaRegion |
| Roles | CDS Coding |
| Sequences | BBa_I746916_sequence (Version 1) |
Description
This is the coding sequence of superfolder GFP (Pedelacq et al (2006): "Engineering and characterization of a superfolder green fluorescent protein", Nature Biotech 24 (1) January 2006).It carries the following amino acid changes with respect to mut3 GFP (E0040), the currently most commonly used GFP in the registry:
S30R, Y39N, F64L, G65T, F99S, N105T, Y145F, M153T, V163A, I171V, A206V
Its in-vivo properties are considerably improved with respect to mut3 - it develops fluorescence about 3fold faster than mut3 GFP and reaches 4fold higher absolute fluorescence levels. Fluorescenct colonies can be identified with the naked eye even without UV or blue light illumination (that is to say the amount of blue light in normal daylight or lablight is sufficient).
Additionally it is more stable in vitro and refolds faster after in vitro denaturation with respect to mut3 GFP.
Note:
Superfolder GFP is available in constructs driven by the pBAD and T7 promoters: part numbers I746908 and I746909 respectively. Additionally 6-his tagged versions for protein purification exist: I746914 (pBAD driven) and I746915 (T7 driven).
Notes
Codon optimisation before de novo synthesis was carried out for both, E.coli and Bacillus subtilis.Source
Superfolder GFP was originally described by: Pedelacq et al (2006): "Engineering and characterization of a superfolder green fluorescent protein", Nature Biotech 24 (1) January 2006This version was synthesised de novo (by Geneart).
