The ubiquitin proteolytic system is an important selective proteolytic system of the celler proteolytic systems, a number of them were identified as a ubiquitin chain assembly factor-E4. The U-box protein is a new family ubiquitin-protein ligase(E3), which determine the substrate specificity of ubiquitination. The U-box is a domain of 70 amino acids that is highly conserved among yeast, plant and animals, but more U-box proteins were found in plants than in animals.

泛素系统是选择性降解细胞内蛋白质的重要系统之一，U-box蛋白质是此系统中决定底物特异性识别的一种新型E3蛋白质，部分U-box蛋白质属于泛素链聚集因子-E4.U-box结构域大约由70个氨基酸残基构成，在酵母、植物和动物等真核生物中保守存在，但植物中的数目远多于动物中。

This illustrated that GFP gene was expressed in the yeast ceil.

与其他酵母评价体系相比，以GFP为报告基因评价EEH不需要破坏细胞壁，也不需要底物，可在96孔板中完成，这为高通量筛选EEH化合物奠定了基础。

In the presence of DMSO as co-solvent and under vigorous agitation, baker\'s yeast in water was found to reduce substituted fluorenones to the corresponding fluorenols in good to excellent enantioselectivies (52%~ 100% ee). The experimental results clearly revealed that when mass transfer limitations are overcome, baker\'s yeast is able to reduce even highly sterically hindered ketones, such as substituted fluorenones.

First, through monofactorial experiment, we studied the influences of pH, temperature and substrate concentration on acidic trehalase activity of baker's yeast. Then we designed an orthogonal experiment to detective the optimal condition of ascertaining acidic trehalase activity. The optimal conditions are: substrate concentration 1.6%, pH 4.0, temperature 30 and seed volume 0.02g/mL compressed yeast.
