mCherry_BSU Plasmid

This part is an expression vector for Bacillus subtilis that produces codon-optimized mCherry_BSU, for integration into Bacillus subtilis at the AmyE loci (BBa_K143001). mCherry_BSU is under pVeg expression (BBa_K143012), the strongest constitutive promotor known in B. subtilis. Plasmid expresses kanamycin resistance in B. subtilis, and ampicillin resistance for cloning in E. coli.

mCherry_BSU has an excitation peak at 585 nm and a peak emission at 615 nm. Color is readily visible in E. coli and B. subtilis in under 12 hours of incubation.

This plasmid successfully integrates into B. subtilis and produces mCherry_BSU at levels that can be quantified using a fluorescent plate reader. Transformation was performed using xylose inducible competent B. subtilis, and plated on selective kanamycin media (20ug/mL). When cloning in E. coli, the E. coli may be red, as they will non-discriminately express the mCherry_BSU. E. coli transformed with this plasmid have been clearly red under natural light for the duration of their lifetime and does not appear to degrade. Transformed B. subtilis colonies may appear weakly red under natural light. E. coli liquid cultures may appear red to the naked eye, while B. subtilis liquid cultures likely will not appear red.


The RBS for expression of mCherry in this vector is strong.

The mCherry does not have a degredation tag.
