csgAα-aeBlue fusion protein with glycine-serine linker

When csgA-alpha fusion chromoproteins are expressed in a culture of E. coli which is then co-cultured with cells secreting csgA-gamma(BBa K4322006), polymers of csgA-alpha-chromoprotein and csgA-gamma will form. The fibrin knob domain/alpha (BBa K4322001) and the fibrin hole domain/gamma (BBa K4322002) will interact (as they do in fibrin [1]) to form long polymers that are covalently linked to chromoproteins [2]. This part is a fusion of the csgA-alpha fusion protein (BBa_K4322005), a glycine-serine linker sequence, and the aeBlue chromoprotein (BBa_K864401).
