cjBlue, green chromoprotein

This chromoprotein from the Cnidopus japonicus sea anemone, cjBlue, naturally exhibits dark green color when expressed. Compared to some 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 24-48 hours of incubation. The sequence is codon optimized for expression in E coli.
