asPink, pink chromoprotein (incl RBS)

This chromoprotein from the coral Anemonia sulcata, asPink (also known as asCP or asFP595), naturally exhibits strong color when expressed. The protein has an absorption maximum at 572 nm giving it a pink/purple color visible to the naked eye. The strong color is readily observed in both LB or on agar plates after less than 24 hours of incubation. The protein asPink has significant sequence homologies with proteins in the GFP family.

Usage and Biology

This part is useful as a reporter.

iGEM13_Uppsala: Expression of chromoproteins. The images above show E coli constitutively expressing meffRed BBa_K1033922, aeBlue BBa_K1033929, tsPurple BBa_K1033905, asPink (asCP) BBa_K1033927, fwYellow BBa_K1033910, meffBlue BBa_K1033902, meffRed BBa_K1033922 and scOrange BBa_K1033913.

Source

The protein was first extracted and characterized by Lukyanov et. al. 2000 under the name asFP595 (GenBank: AAG02385.1). This version is codon optimized for E coli by Genscript.
