| 1. | Collect the 20 ? l of dna and enzyme mixture on the bottom of the tube by brief centrifugation 稍为离心使dna与酵素的混合液集中于管子底部。 |
| 2. | The lack of the sugar moiety could cause changes in the structure of the active site of the enzyme resulting in the observed modifications of the kms 去除糖基会使葡萄糖氧化酵素的活化位构造改变,因而产生所观察到的km值变化。 |
| 3. | What enzyme / organism was used as the biocatalyst and how was it selected ? for a purified enzyme process , include the source organism for the enzyme 什么样的酵素/生物被用来做为生物触媒,且如何选择?对于纯化酵素的程序,则包括酵素的来源种属。 |
| 4. | Natural shiitake complex has been shown to work similarly to an enzyme found naturally in the skin to accelerate cell turnover and renewal for healthy , younger - looking skin 自然的香菇萃取物经证明有类似酵素的作用,可以加速皮肤的新陈代谢,获得更为健康年轻的皮肤外观。 |
| 5. | A corollary has been that proteins , in addition to their structural and enzymatic roles in cells , must be the primary agents for regulating the expression , or activation , of genes 在这个推论下,蛋白质除担负细胞结构和酵素的角色外,必定也是调控(或活化)基因表现的主要因子。 |
| 6. | But if a drug is made of protein ? as most agents produced using biotechnology are ? it also has to evade the activity of protein - destroying enzymes called proteases 但如果药物是蛋白质类的物质(就像是利用生物技术制造的多数药物) ,就还得躲过蛋白酶这种蛋白质分解酵素的攻击。 |
| 7. | Because beta - secretase clearly falls into this family , researchers were able to exploit the vast knowledge about these proteases , leading to a very detailed understanding of this enzyme and how it might be shut down 因为分泌酶显然是这个家族的成员,研究人员可以善用他们对这个家族的丰富知识,深入理解这个酵素的功能,以及可能的抑制方法等。 |
| 8. | Genetic studies suggest that blocking the enzyme ' s activity will not lead to harmful side effects ; deletion of the gene encoding beta - secretase in mice eliminated a - beta formation in the rodents ' brains without causing any apparent negative consequences 遗传研究的结果暗示,阻断这个酵素的活性,并不会造成有害的副作用;移除小鼠的分泌酶基因,小鼠的脑部就无法制造出a - ,但却不会造成任何明显的负面后果。 |
| 9. | “ in the future , research in molecular biology may provide improved techniques for manipulating macromolecules , ” adleman wrote in a seminal 1994 scientific paper describing the dna experiment . “ research in chemistry may allow for the development of synthetic designer enzymes 1994年,艾德曼在这篇说明他启发性的dna实验科学论文中写到:未来,分子生物学的研究成果,将可改良操控巨分子的技术;化学方面的研究将可促成合成设计酵素的发展。 |
