Part:BBa_E1010

**highly** engineered mutant of red fluorescent protein from Discosoma striata (coral)

monomeric RFP: Red Fluorescent Protein. Excitation peak: 584 nm Emission peak: 607 nm

Usage and Biology

Robert E. Campbell started with Discosoma RFP (DsRed) and evolved a faster folding, monomeric variant. See paper listed in source. Codon optimized for expression in bacteria (?? DE)

iGEM11_Uppsala-Sweden: Expression of chromoproteins. The images above show E coli constitutively expressing amilCP BBa_K592009 (blue), amilGFP BBa_K592010 (yellow) and RFP BBa_E1010 (red).

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.
