This is an improve part.This gene is a cold resistant gene from the Arctic cryophile Polaribacter irgensii.It can largely increase the cold resistance of bacterias.CDS sequence optimization in (BBa_K538004) is better suited for expression in Bacillus megaterium and we add a 6*His tag at the C end.After that, the promoter (BBa_K143012) and RBS (BBa_K090505) were combined.
