2.7.7.2 | nutrition |
industrial production of FAD and FMN as nutrient additives, pharmaceuticals and biochemical agents |

2.7.7.2 | synthesis |
modular engineering of Escherichia coli to improve flavin production and the conversion ratio of riboflavin RF to FMN/FAD. The RF operon and the bifunctional RF kinase/FAD synthetase are divided into two separate modules and expressed at different levels to produce different RF:ribF. The best strain respectively produces 324.1 and 171.6 mg/l of FAD and FMN in shake flask fermentation. Error-prone of the RibF gene further increase production up to 586.1 mg/l in shake flask cultivation |

2.7.7.2 | synthesis |
purified recombinant FADSCf can be used for the biosynthesis of FAD. Under optimized conditions (0.5 mM FMN, 5 mM ATP and 10 mM Mg2+), the production of FAD reaches 80 mM per mg of enzyme after a 21-hour reaction |

2.7.7.2 | synthesis |
the enzyme is used for the preparation of flavin mononucleotide (FMN) and FMN analogues from their corresponding riboflavin precursors, which is performed in a two-step procedure. After initial enzymatic conversion of riboflavin to FAD by the bifunctional FAD synthetase, the adenyl moiety of FAD is hydrolyzed with snake venom phosphodiesterase to yield FMN. The engineered FAD synthetase from Corynebacterium ammoniagenes with deleted N-terminal adenylation domain is a biocatalyst that is stable and efficient for direct and quantitative phosphorylation of riboflavin and riboflavin analogues to their corresponding FMN cofactors at preparative-scale |
