Efficient Optimization of Gluconobacter oxydans Based on Protein Scaffold-Trimeric CutA to Enhance the Chemical Structure Stability of Enzymes for the Direct Production of 2-Keto-L-gulonic Acid

<div>Production of 2-KLG by CutA-based engineered strain and the control strain at different temperatures. A, C, and E are OD600 and 2-KLG production of G. oxydans/pGUC-tufB-sdh-GGGGS-sndh at 30°C, 35°C, and 37°C, respectively. B, D, and F are OD600 and 2-KLG production of G. oxydans/pGUC-tufB-SH3-sdh-GGGGS-sndh-tufB-SH3lig-(GGGGS)2-cutA at 30°C, 35°C, and 37°C, respectively. Error bars represent the standard deviation of three biological replicates.</div>
