Part:BBa_K1033933

asPink, pink chromoprotein

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.

asPink does not exist as CDS only but only as RBS-asPink (BBa_K1033927) and J23110-RBS-spisPink (BBa_K1033926).

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.
