Genome-integrated engineering of Escherichia coli Nissle 1917 enables sustained gut-local biosynthesis of 5-hydroxytryptophan
A genome-integrated engineered probiotic system enabling gut-local biosynthesis of 5-HTP was developed and results showed that the hTPH2 hydroxylation module, together with the BH4 biosynthesis and regeneration system, supported 5-HTP biosynthesis in EcN.
