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.

Usage and Biology

This part is useful as a reporter.

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.

Figure 1. under blue light excitation, The left one is fwYellow


When we used the microplate reader to measure the excitation light and absorbed light, we found that the spectrum of fwYellow is too narrow. Due to the low precision of the instrument, it is impossible to accurately measure its excitation light and emission light. The excitation light is around 522 nm and the emission is about 536 nm.

Characterization: NWU-China 2020

The NWU-ChINA-A 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).

Due to the low precision of the instrument, it is impossible to accurately measure its excitation light and emission light. The excitation light is around 511 nm and the emission is about 511 nm.

Functional Parameters: Austin_UTexas

BBa_K1033910 parameters

Burden Imposed by this Part:

Burden Value: 0.2 ± 2.4%

Burden is the percent reduction in the growth rate of E. coli cells transformed with a plasmid containing this BioBrick (± values are 95% confidence limits). This BioBrick did not exhibit a burden that was significantly greater than zero (i.e., it appears to have little to no impact on growth). Therefore, users can depend on this part to remain stable for many bacterial cell divisions and in large culture volumes. Refer to any one of the BBa_K3174002 - BBa_K3174007 pages for more information on the methods, an explanation of the sources of burden, and other conclusions from a large-scale measurement project conducted by the 2019 Austin_UTexas team.

This functional parameter was added by the 2020 Austin_UTexas team.
