Generally, the method of determining whether the redox partner is suitable is through tedious steps such as the construction of plasmids, heterologous expression, construction of catalytic systems, and detection of conversion rate after catalysis. Therefore, we wanted to find a convenient way to do a quick screening. We used the fluorescent protein sfGFP to successfully construct a sensor to detect redox partners. sfGFP is a superfolder fluorescent protein that emits green light when irradiated with ultraviolet light. What is special about it is that it can be broken into two parts. We divide sfGFP into sfGFP-1-10 and sfGFP-11, and although these two parts are cut off, there is an interaction force between them, and as long as they are properly folded in space, they will emit light again. Thus, four iron redox proteins are fused to the N-terminus of sfGFP-1-10 and Olep to the C-terminus of sfGFP-11, respectively, to obtain the recombinant plasmid pRSFDuet-BM3-GFP-1-10-GFP-11-oleP, pRSFDuet-camA-camB-GFP-1-10-GFP-11-oleP, pRSFDuet-FdR_0978-Fdx_1499-GFP-1-10-GFP-11-oleP, pRSFDuet-petH-petF-GFP-1-10-GFP-11-oleP The above four recombinant plasmids are converted to BL21(DE3) to obtain recombinant strains G2 strain to G5 strain.
