| 1 | Enzymatic synthesis of bioactive compounds by Rhus laccase from Chinese Rhus vernicifera显示文摘A simple one step synthesis of pinoresinol and its derivatives-active components of Du-Zhong(Eu-commia ulmoides) -from coniferyl alcohol and p-courmaryl alcohol with higher yields was achieved by Rhus laccases(RL) catalysis in water miscible organic solvents. Biomacromolecules dehydro-genative polymers(DHP) were only synthesized by fungal laccases,not by RL. The structures and the reaction mechanism were discussed to promote the understanding of the function of laccases in the process of lignin biosynthesis. | AKIYAMA Kazuhiro MIYAKOSHI Tetsuo | 2007 | Science China Chemistry2007，50，2： | 4 |
| 2 | Enzymatic catalysis of 2,6-dimethoxyphenol by laccases and products characterization in organic solutions显示文摘2,6-Dimethoxyphenol (DMP) as a substrate was widely used in determination of laccase activity. It is surprising, however, that its catalyzed oxidation products have not been completely determined until now. Studies were thus conducted on Rhus laccase (RL) and immobilized Rhus laccase (IRL)-catalyzed oxidation reactions of 2,6-dimethoxyphenol in water-organic solvent systems. These reactions pro- ceeded well in water-(im)miscible organic solvent systems pre-saturated with water. Only one product, 3,3′,5,5′-tetramethoxy-1,1′biphenyl-4,4′-diol (TMBP), was produced by RL catalysis, and it was thor- oughly characterized by FT-IR, NMR, GC-MS, etc. A simple enzymatic mechanism of this reaction is proposed. | MIYAKOSHI Tetsuo | 2008 | Science China Chemistry2008，51，7： | 2 |
