Usage and Biology

After obtaining the best redox partners PetH/PetF, we performed alanine scanning on petF to speculate which sites had a greater impact on its electron transport capacity. Finally, we found that after mutations in seven of them, the electron transport effect would change greatly, so we mutated the amino acids of these sites into other 19 amino acids by modeling, and selected 23 of them to get better results. (Site-directed Mutagenesis parts can be search from BBa_K4759053 to BBa_K4759075, and constructed modeling screening for redox partners can be search from BBa_K4759076 to BBa_K4759099)

We conducted control tests with the positive control group, negative control group, and wild-type strains, and finally selected 9 mutants with the highest fluorescence intensity for subsequent catalytic verification by detecting their green fluorescence intensity.

By verifying the catalytic ability, we found that the substrate conversion of D68P was higher than that of the wild type in the nine strains with high fluorescence intensity, reaching 89.2%.
