Part:BBa_K592009

amilCP, blue chromoprotein

This chromoprotein from the coral Acropora millepora, amilCP, naturally exhibits strong color when expressed. The protein has an absorbance maximum at 588 nm giving it a blue/purple color visible to the naked eye, thereby requiring no instruments to observe. The strong color is readily observed in both LB or agar culture, in less than 24 hours of incubation.

This part has been adaptated to B. subtilis with a LVA tail. by the UPMC-Paris Team in 2016. (see part BBa K2180019)

Usage and Biology

This part is useful as a reporter. In the pictures below it's built into BBa_K592015.
