结果表明，上述方法进行玉米须多糖提取的适宜条件是：纤维素酶用量5%，酶解温度50℃，水浴振荡170 min；再经超声处理5 min后，总糖得率可提高35.52%。

Thus, the "yellow enzyme" is isolated as a conjugated protein in which the non-amino acid moiety is riboflavin phosphate, while catalase is an iron-porphyrin-containing protein

The results implied that NO/ROS-induced ABA accumulation come from de novo synthesis pathway rather than degration of conjugated forms. The protein synthesis inhibitor actidone blocked the NO-induced ABA accumulation while having no effects on ROS-induced ABA accumulation, indicating that the action of NO was gene-expression dependent and that of ROS was gene-expression independent. These results suggested that NO may serve as a stress signal in the regulation of ABA-biosynthesis and ROS may serve as substrate in ABA biosynthesis or be involved in the regulation of enzyme activities.

1ABA合成抑制剂fluridone抑制ROS和NO诱导的ABA积累，表明NO／ROS诱导的ABA积累来源于ABA的从新合成而不是已有结合态ABA的代谢；(2)蛋白质合成抑制剂环己亚胺可以抑制NO诱导的ABA积累而对ROS诱导的ABA积累没有影响，说明NO的作用涉及基因表达而ROS的作用与基因表达无关，暗示NO的作用方式可能是作为一种干旱胁迫信号物质参与ABA合成的调节，而ROS则可能参与了相关酶活性的调节或直接参与了ABA合成的底物反应。

Studied on the changes of pH and enzyme activities in soils in different years of panax Ginseng C.A.

通过对人参、西洋参不同栽培年限土壤的pH和酶活性变化的研究，结果表明：随着人参栽培年限的延长，土壤pH先升高后降低，2年生时土壤pH达最高5.94，随后降低；西洋参床土pH先升高，到3年时达最高5.53，随后降低。

Methods In 50 cases of patients after treatment of artificial kidney and 54 healthy volunteers, the prevalence of HHV-7 in peripheral blood mononuclear cell and cell-free viral DNA in plasma was tested by nested polymerase chain reaction assay; the product of PCR was digested by restricted enzyme EcoR I to identify its specificity.

采用巢式聚合酶链反应对50例肾透析病人和54例正常健康人PBMC和血浆标本中HHV-7 DNA进行定性检测；用限制性核酸内切酶EcoRⅠ对PCR产物进行酶切图谱分析以确定扩增产物的特异性。

The effect of Tween 80 addition, enzyme loading and substrate concentration on the re-adsorption of cellulases, which hydrolyzed the corncob after the pretreatment by soaking in aqueous ammonia, was studied in this paper.

论文通过实验方法，考察了重吸附法回收纤维素酶中的一些因素（表面活性剂浓度、加酶量和底物浓度）对回收利用效果的影响规律，得到了较优的工艺参数范围，对于解决纤维素酶的回收利用有一定参考价值。

Smokers with low levels of the enzyme were five to 10 times more likely to develop lung cancer than smokers with the highest levels, researchers at Israel's Weizmann Institute found.

在以色列 Weizmann 研究所的研究人员发现，体内含某种酶水平过低的瘾君子患上肺癌，要比含该种酶高的烟民多上5－10成的几率。

The crystalline body of the enzyme had been attained in the Turku biological technology center, Finland.

由芬兰Turku生物技术中心完成该酶的晶体结晶，为今后该酶三维空间结构的分析和同类型酶蛋白的结晶打下了基础。

Melanin is synthesized only in the colder parts of the body because Siamese cat bears temperature sensitive allele for enzyme producing melanin.

因为暹罗猫产生黑色素的酵素之等位基因为温度敏感性，所以黑色素只在身体较冷的部位合成。

The results show that during the development of the oriental tobacco leaves, the activity of acid invertase was decreased; the changes of GS reached its peak in the 20dans in Samsun, but in the 30dans in Basma and Canik ;the activity of PAL was decreased in the 30dans; The content of total nitrogen was decreased with the mature leaves, but nicotine、total carbon and soluble total sugar were increased. Different varieties, carbon and nitrogen metabolism key enzyme activity and the content of metabolites were different.

结果表明，在香料烟叶片发育过程中，酸性转化酶的活性均呈下降趋势；谷氨酰胺合成酶的活性Samsun品种在20d叶龄时最高，而Basma和Canik在30d叶龄时最高；苯丙氨酸解氨酶的活性均表现为30d时最低；随着叶片成熟总氮含量降低，烟碱含量升高，总碳、可溶性总糖随着叶片成熟其含量呈升高趋势；品种不同，碳氮代谢关键酶的活性及代谢产物的含量变化均有很大差异。
