additional information | engineering of a recombinant Escherichia coli strain expressing the davB and davA genes for bioconversion of L-lysine to 5-aminovaleric acid resulting in low levels of 5-aminovalerate. Development of metabolically engineered Corynebacterium glutamicum strains for enhanced fermentative production of 5-aminovalerate from glucose. Expression of the Corynebacterium glutamicum codon-optimized davA gene fused with His6-Tag at its N-terminus and the davB gene as an operon under a strong synthetic H36 promoter (plasmid p36davAB3) in Corynebacterium glutamicum strain BE (pJS38) enables the most efficient production of 5-aminovalerate. The construct containing the His6-tagged variant produces substantially more 5-aminovalerate compared to that produced using the construct lacking the His-tag, possibly because of the improved stability afforded by the 5'-modification, which results in higher expression of the davAB genes in the recombinant Corynebacterium glutamicum BE strain. Deletion of the gabT gene (EC 2.6.1.19), encoding 4-aminobutyrate aminotransferase, improves the 5-aminovalerate production | Pseudomonas putida |
