meffBlue, blue chromoprotein (incl RBS)
This chromoprotein from the coral Montipora efflorescens, meffBlue (also known as Rtms5), naturally exhibits strong color when expressed. The protein has an absorption maximum at 592 nm giving it a blue color visible to the naked eye. 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. The protein meffBlue has significant sequence homologies with proteins in the GFP family.
Usage and Biology
This part is useful as a reporter.
Montipora efflorescens. The protein was first extracted and characterized by Beddoe et. al. under the name Rtms5 (UniProtKB/Swiss-Prot: P83690.2). This version is codon optimized for E coli by Genscript.
