Enzymatic synthesis of vanillin.
Due to increasing interest in natural vanillin, two enzymatic routes for the synthesis of vanillin were developed. The flavoprotein vanillyl alcohol oxidase (VAO) acts on a wide range of phenolic compounds and converts both creosol and vanillylamine to vanillin with high yield. The VAO-mediated conversion of creosol proceeds via a two-step process in which the initially formed vanillyl alcohol ...
متن کاملBiocatalytic synthesis of vanillin.
The conversions of vanillic acid and O-benzylvanillic acid to vanillin were examined by using whole cells and enzyme preparations of Nocardia sp. strain NRRL 5646. With growing cultures, vanillic acid was decarboxylated (69% yield) to guaiacol and reduced (11% yield) to vanillyl alcohol. In resting Nocardia cells in buffer, 4-O-benzylvanillic acid was converted to the corresponding alcohol prod...

15 صفحه اولSalicylic acid induces vanillin synthesis through the phospholipid signaling pathway in <i>Capsicum chinense </i>cell cultures
Signal transduction via phospholipids is mediated by phospholipases such as phospholipase C (PLC) and D (PLD), which catalyze hydrolysis of plasma membrane structural phospholipids. Phospholipid signaling is also involved in plant responses to phytohormones such as salicylic acid (SA). The relationships between phospholipid signaling, SA, and secondary metabolism are not fully understood. Using...
متن کاملHeurstic search for metabolic engineering: de novo synthesis of vanillin
We present the application of heuristic search to in silico metabolic pathway engineering. In particular, we discuss a new computational approach to elucidate complex pathways and to address the practical challenge of combinatorial complexity in pathway inference. We have implemented this approach in a new computational framework, called PathMiner, which is useful for designing metabolic engine...
