Super Yellow Fluorescent Protein 2 (SYFP2)

This part codes for the bright yellow fluorescent protein SYFP2. SYFP2 is a GFP based monomeric protein with optimized folding and maturation and a narrow fluorescence emission spectrum with a maximum at 515 nm. Bacteria expressing SYFP2 are reported to be 12 times brighter than those expressing EYFP(Q69K) and almost 2-fold brighter than bacteria expressing Venus (Kremer et al 2006). Mutations compared to wtGFP amino acid sequence (GenBank Accession number M62653) are F46L F64L S65G S72A M153T V163A S175G T203Y A206K. See the article listed in references. The sequence has been codon optimized for expression in E coli by DNA 2.0.

Kremers et al reported the following data:

Excitation peak: 515 nm. Emission peak: 527 nm. Relative brightness to EYFP2(Q96K) in E coli: 12.0. Extinction Coefficient (M-1 cm-1): 101000. Quantum Yield: 0.68.

Usage and Biology

This part is useful as a reporter.
