Bacterial Biosynthesis of a Multipotent Stilbene

Bacterial biosynthesis of a multipotent stilbene.

Novel pathway for bacterial metabolism of bisphenol A. Rearrangements and stilbene cleavage in bisphenol A metabolism.

Bisphenol A (BPA) is metabolized by a Gram-negative aerobic bacterium via a novel pathway involving oxidative skeletal rearrangement of the BPA. Oxidation of the aliphatic methyl group of BPA leads to coproduction of the methyl-hyroxylated 2,2-bis(4-hydroxyphenyl)-1-propanol and a skeletally rearranged triol 1,2-bis(4-hydroxyphenyl)-2-propanol. The major route of metabolism (> 80%) is through t...

9 Enzymology of Bacterial Lysine Biosynthesis

Lysine is an essential amino acid in the mammalian diet, but can be synthesised de novo in bacteria, plants and some fungi (Dogovski et al., 2009; Hutton et al., 2007). In bacteria, the lysine biosynthesis pathway, also known as the diaminopimelate (DAP) pathway (Fig. 1), yields the important metabolites meso-2,6-diaminopimelate (meso-DAP) and lysine. Lysine is utilised for protein synthesis in...

Biosynthesis of plant-specific stilbene polyketides in metabolically engineered Escherichia coli

BACKGROUND Phenylpropanoids are the precursors to a range of important plant metabolites such as the cell wall constituent lignin and the secondary metabolites belonging to the flavonoid/stilbene class of compounds. The latter class of plant natural products has been shown to function in a wide range of biological activities. During the last few years an increasing number of health benefits hav...
