An expression device for fusion protein of Formamidase and Phosphite dehydrogenase
The BBa_K2325001 harbors a coding sequence of and formamidase(FOR) and phosphite dehydrogenase (PTDH) with a linker between them, which can simultaneously catalyzes the conversion of formamide to ammonia and phosphite to phosphate, respectively. The device also contains GST tag for increasing the solubility of exogenous protein.
Gel analysis
M：1kb DNA Marker P;
1: plasmid from BL21(DE3) (pGEX-for-ptx);
2&3: plasmid from BL21(DE3) (pETDuet-for-ptx).
Usage and Biology
Figure 1. Growth curves of E.coli (with two ways of constructed plasmids possessing the formamidase gene and phosphite dehydrogenase gene) in a basal MOPS medium (Na2HPO3•5H20 (1.32mM) , NH3CO (200mM)).
The results showed that the growth of recombinant strains of both construction ways are encouraging, indicating the recombinant strains were able to utilize formamide and phosphite at the same time, while the negative control group was unable to grow normally due to the lack of nitrogen and phosphorus sources.
