Part:BBa_K1033910

fwYellow, yellow chromoprotein

This chromoprotein (also known as FezziwigYFP) naturally exhibits strong color when expressed. Compared to many other chromoproteins, such as amilCP (BBa_K592009), amilGFP (BBa_K592010), spisPink (BBa_K1033932), asPink (BBa_K1033933) and aeBlue (BBa_K864401), the color development is slower. The color is readily observed in both LB or on agar plates after 24-64 hours of incubation.

Characterization: NWU-China 2019

The NWU-China team overexpressed fwYellow protein in E. coli and extracted and purified. The maximum absorbance was measured in a 96-well plate using a microplate reader (Synergy 2).

At the same time, fwYellow can emit strong fluorescence under blue light excitation.
