Riboflavin enhancing parts
We construct this part based on BBa_K169011 and BBa_K1172303.
Fig1.The design of this part.
Based on co-factor model, EET pathway points out that FMN plays a critical role in electron transfer. Through the study by Dr. Tao Chen, they have weakened the RBS upstream of ribC to divert more of the material flux to RF production. Based on their viewpoint, we got further to design a strong RBS sequence upstream of the ribC and we rename the new part as EC10*(BBa_K1696010). The yield of EC10* reached 90 mg/L(as shown in Figure2). The strong RBS before ribC sequence can lead to the FMN accumulation while riboflavin consumes a bit, which may in turn, result in increase both for riboflavin and FMN as a whole.
