It has unique substrate specificity, and required minimal sugar chain in the degradation direction and synthesis direction of trisaccharide and disaccharide separately.

该酶具有独特的底物特异性，其降解方向和合成方向所需的最小糖链长度分别为三糖和二糖，均比普通的葡聚糖磷酸化酶少一个糖基以上。

Studies also indicated that genistein exsists not only in soybeans but also in many kinds of plants such as vegetables and fruits.As a potential anticancer agent, the actional mechanisms of genistein mainly includes as follows:First, genistein can depress the activity of protein tyrosine kinase and transduction pathways for the phosphorylation of receptors and mitosis signal. So genistein can lead to cells' proliferation depressed. Second, genistein has minimal effects of phytoestrogens. It can be combined with estrogen receptor and improve the synthesis of cellular sex hormone binding glulobin, and improve the activity of UDP-glucuronyl transferase. Through these pathways, it can inhibit the cell activity of breast cancer and prostate cancer.

作为一个很有潜力的抗肿瘤物质，三羟异黄酮的作用机制主要包括：①抑制蛋白酪氨酸激酶活性，可阻抑PTK引起的受体磷酸化和有丝分裂的信号传递，导致癌细胞增殖受抑；②弱雌激素作用：可通过与体内雌激素受体结合，并可增加细胞内性激素结合球蛋白的合成，增加UDP-葡糖醛酸转移酶的活性等途径抑制乳腺癌和前列腺癌细胞活性；③拓扑酶Ⅰ和Ⅱ抑制剂，抑制细胞活性；④上调细胞周期性负性调节因子P21WAF1/CIP1的表达，使之负性调节因子作用增强；⑤可阻止胰岛素样生长因子-Ⅰ、肝细胞生长因子和神经生长因子的作用而抑制肿瘤生长；⑥其他：抗氧化作用、抑制热休克蛋白、诱导细胞凋亡、抑制新生血管生成和抑制多种耐药相关蛋白等。

Malt extract, kolbach index, diastatic power and malt viscosity are the major traits closely related to the quality of malt barley, and they themselves are dominantly affected by carbohydrates, protein content and their components, and the relevant enzymes in grains.

麦芽浸出率、糖化力、库尔巴哈值、粘度值、蛋白质和β-葡聚糖含量是衡量啤酒大麦品质的主要指标，而β-葡聚糖酶、β-淀粉酶等一些水解酶类又与上述品质性状密切相关。

From molecular structure of chemistry,picric in stevioside,sweetness,the relation between sweetness,aglycone join position and join glucosyl quantity were discussed in the paper.

本文从分子化学结构的角度出发，论述分析了甜菊糖苷甜中带苦涩后味的根本原因，甜度、甜味与苷元的C连接部位和连接葡糖基数的关系；对于现今改进甜菊糖苷的苦涩味的酶化方法，作了深入的比较、论证，并指出新的科学技术方法。

The functions and interactions of DNA methylation regulating factors, the establishment, mantainace and removement mechanisms of DNA methylations are reviewed in this paper.

DNA转葡糖基酶有去甲基化活性从而减轻基因沉默。文章综述了以上植物DNA甲基化调控因子的生物学功能及其之间的相互作用和近年来的研究进展，以更好的理解DNA甲基化的建立、保持和去除的机制。

Feeding for 24h by third instar larvae of the maize stalk borer induced farnesyl pyrophosphate synthase gene expressing, but had no effect on expression of AOC, BX9, PAL and PR2a genes and DIMBOA content.

3玉米螟3龄幼虫处理24h能诱导玉米根中法呢烯基焦磷酸合成酶基因表达，但不能诱导丙二烯氧化物环化酶、β－1，3葡聚糖酶基因（PR2a）、糖基转移酶（BX9）、苯丙氨酸转氨酶基因表达，同时对第二叶和根中丁布含量无显著影响，使第二叶对羟基苯甲酸及第三叶丁布、对羟基苯甲酸、香草酸含量显著降低。
