Research Interest
Aromatic compounds like phenylethanol and phenylacetic acid are key flavors in most fermentation foods. Their biosynthesis pathway was one of the most complicate metabolic pathways in microorganisms. A phenylpyruvate derivatives producing chasis was constructed using systems level engineering in my previous study (Process Biochemistry 49 (2014) 751-757), then the metabolic pathways and regulation sites were reviewed for aromatic compounds synthesis (Metabolic Engineering 32 (2015) 55-65). A novel recycle l-phenylglycine synthetic pathway was also developed (Journal of Biotechnology 186 (2014) 91-97). Now I found that Saccharomyces cerevisiae CRWY for Chinese rice wine brewing possessed a distinct metabolic regulation mechanism in ?-phenylethanol synthetic pathway, especially the Pha2p was feedback inhibited by L-phenylalanine.
