eforRed, red chromoprotein
This chromoprotein eforRed naturally exhibits red/pink color when expressed. The color is slightly weaker than RFP. On agar plates and in liquid culture, the color is readily visible to naked eye in less than 24 hours of incubation. The DNA was codon-optimized for expression in E.coli and synthesized by the Korean company Bioneer Corporation.
Important: This part is not available in the registry yet, however, the same part is available from the registry with the RBS B0032: BBa_K1073023.
Usage and Biology
This part is useful as a reporter.
Peking iGEM 2016 has fused this part with triple spytag. The fused protein is participate in Peking’s polymer network. By adding this protein, the whole polymer network become visible in most conditions.

iGEM12_Uppsala_University: Left picture: Visual color expression of eforRed (BBa_K592012).
Right picture: The Uppsala chromoprotein collection and RFP. The image shows pellets of E coli expressing chromoproteins eforRed BBa_K592012, RFP BBa_E1010, cjBlue BBa_K592011, aeBlue BBa_K864401, amilGFP BBa_K592010 and amilCP BBa_K592009.
An improved part has been constructed. Since this part is a coding sequence, we added a RBS which is on the upstream of sfGFP BBa_K515005 and terminator BBa_B1006 by PCR. What's more, our device have a stem-loop structure(called Target) following the constitutive promoter J23119, to achieve further control of eforRed expression.
