Part:BBa_K592012

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. If you want to learn more about Peking’s polymer network and the role of mRFP in this network, please click here https://parts.igem.org/Part:BBa_K1989049", https://parts.igem.org/Part:BBa_K1989050" or https://parts.igem.org/Part:BBa_K1989051".

J23119+Target3+eforRed BBa_K2285012
J23119+Target1+eforRed BBa_K2285016

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.
