For production of genistein from N-acetylcysteamine-attached p-coumarate (p-coumaroyl-NAC) supplemented to the medium, a chalcone synthase (CHS) gene from Glycyrrhiza echinata, a chalcone isomerase (CHI) gene from Pueraria lobata, and an isoflavone synthase (IFS) gene from G. echinata were placed under the control of the galactose-inducible GAL promoters in pESC vector and were introduced in Saccharomyces cerevisiae. When the recombinant yeast cells (0.5 g wet weight) were used as "enzyme bags" and incubated at 30 degrees C for 48 h in 100 ml of the buffer containing galactose and 1 mM (265 mg/l) p-coumaroyl-NAC, ca. 340 microg genistein/l was produced. Another system consisting of two enzyme bags was also generated for the purpose of production of genistein from tyrosine. One enzyme bag was an Escherichia coli cell containing a phenylalanine ammonia-lyase gene from a yeast, a 4-coumarate/cinnamate:CoA ligase gene from the actinomycete Streptomyces coelicolor A3(2), the CHS gene, and the CHI gene, in addition to the acetyl-CoA carboxylase gene from Corynebacterium glutamicum, all of which were under the control of the isopropyl-beta-D-thiogalactopyranoside-inducible T7 promoter, and thus producing (S)-naringenin from tyrosine. The other enzyme bag was a S. cerevisiae cell containing the IFS gene. Coincubation of the E. coli cells (0.5 g wet weight) and S. cerevisiae cells (0.5 g wet weight) at 26 degrees C for 60 h in 20 ml of the buffer containing 3 mM (543 mg/l) tyrosine as the starting substrate yielded ca. 6 mg genistein/l.

Licorice flavonoid oil (LFO), which contains hydrophobic flavonoids from Glycyrrhiza glabra LINNE, is a new ingredient for functional foods. In this study, we investigated the anti-obesity action of LFO in diet-induced obese rats. The addition of 2% LFO in a high-fat diet significantly decreased the weight of abdominal adipose tissue and the levels of hepatic and plasma triglycerides. We found that the enzymatic activities of acetyl-CoA carboxylase and fatty acid synthase, the rate-limiting enzymes in the fatty acid synthetic pathway, were significantly decreased by LFO, whereas the enzymatic activity of acyl-CoA dehydrogenase, the rate-limiting enzyme in the fatty acid oxidative pathway, was significantly increased. All our findings suggest that the anti-obesity action of LFO is controlled by regulation of the rate-limiting enzymes in the fatty acid synthetic and oxidative pathways in the liver.
