Data For Our New Favorite Parts
D168A Double Cysteine Mutant of Smallpox Topoisomerase, BBa_K891234
This mutant version of topoisomerase recognizes the YCCTT motif in dsDNA. It cleaves after the last T in this motif, making a single stranded nick, and covalently binds to the 3' phosphate on that thymine.
This part should be paired with GFPT2. This part codes for a 20bp sequence that is complementary to a portion of the genomic GFP coding sequence in E.coli Keio strains.
This part should be paired with GFPT1. This part codes for a 20bp sequence that is complementary to a portion of the genomic GFP coding sequence that comes after the GFPT1 binding site in E.coli Keio strains.
Split Beta-Galactosidase Reporter System
Tested alpha fragment of beta-galactosidase for complementation with the omega fragment in vivo. A construct consisting of Streptavadin-Linker-Alpha fragment was transformed into BL21(DE3) E.coli cells that naturally express the omega fragment of beta-galactosidase. Quadrant streak plate in the presence of X-gal produced dark blue colonies. These results illustrate alpha-omega complementation in vivo. In vivo complementation indicates the ability of the two fragments to fuse into a functional beta-galactosidase unit, indicating that the split beta-galactosidase reporter system module of the biosensor was constructed and can be implemented successfully.

Current Research
Current testing with the split beta-galactosidase system includes time-interval testing of colorimetric response, including quantitative measurements of beta-galactosidase concentration over time, omega fragment negative control testing, and in vitro testing of the alpha and omega fragments linked to streptavadin and Magainin.
