lacI+lacZ+RBS+amylase-RFP+double terminator

Contents :

・The lac promoter and lacZ from BBa_J33207

・The native RBS from BBa_K523001

・The gene codes for the amylase-RFP fusion protein. (BBa_K4032003）

・The double terminator from BBa_B0015

For more information on the amylase gene malS,see NCBI: NC_000913.3.

Usage and Biology

This enzyme hydrolyzes of (1-4)-α-D-glycosidic linkages in polysaccharides containing three or more (1-4)-α-linked D-glucose units. For more information, See NCBI: NC_000913.3.

In the case of this part, Red red fluorescence of RFP is observed with a fluorescence microscope, but isn’t observed under the natural light source.

Design

The lac promoter and the double terminator are added to BBa_K4032006, forming this part.

The lac promoter and the double terminator are from BBa_J04450.

This part was created by In-Fusion method using BBa_J04450 and BBa_K523006 as an insert.

SDS-PAGE

To investigate the expression of amylase-RFP from E. coli and coral, bacteria transformed with BL21(DE3) were cultured in an LB medium containing chloramphenicol. After incubation of E. coli at 37 ℃ and 130 rpm for 16 hours, the cells were inoculated into a new medium and cultured in liquid until the logarithmic growth phase. IPTG was added to a final concentration of 0.2 mM, and E. coli was cultured overnight for 10 hours at 25 ℃ and 130 rpm.

The cultured bacteria were sonicated using Sonication buffer (Phosphate buffer solution (pH 7.0) + 150 mM NaCl + 10% glycerol) and SDS-PAGE was performed.
