Part:BBa_K1890020

GFP with strong constitutive promoter, RBS and terminator

Indroduction

Green fluorescent protein (GFP) from the jellyfish Aequorea victoria. This mutant represents a series of mutations resulting in enhanced maturation and emission [1]. It is expressed under control of the strong constitutive promoter BBa_J23100, strong RBS BBa_B0030 and terminators BBa_B0010 and BBa_B0012.

Construction

This part is based on the part BBa_E0840, which already contains RBS, GFP gene and terminators. By means of PCR we added the strong constitutive promoter BBa_J23100. Two PCR reactions were performed with the following primers (Table 1).

To prevent annealing of the primer containing the promoter, to the BioBrick prefix, a preliminary PCR was performed with a forward primer not containing the BioBrick prefix (Figure 1).
