Part:BBa_K2387001

Monomeric chromoprotein anm2CP controlled by inducible araC/pBAD promoter

In this composite, the coding sequence for anm2CP is under the control of the inducible pBad/araC promoter (BBa_I0500), as well as a strong RBS (BBa_B0034).

Usage and Biology

anm2CP is a monomeric chromoprotein (BBa_K2387000), the only one that is known to be produced in nature. The sequence can be retrived from the genome of the jellyfish Anthomedusae sp. SL-2003 (GenBank, AY485336). It shows a bright pink color when expressed to sufficient concentrations. Its absorbance spectrum shows a pick with a maximum at 572 nm. As other fluorescent proteins and chromoproteins, it has a structure similar to that of GFP, as it can be observed from the structure of KillerRed (PSB 2WIQ) a fluorescent protein evolved from anm2CP. Most chromoproteins are tetrameric, which makes them a bad candidate for protein fusions and other applications. Among other applications, anm2CP would be able to be split in order to be used in bimolecular complementation techniques.
