查询词典 helix

The results show that all the hmgr genes from pigs, cattle and chickens are astable enzyme proteins with the same gene sequence characteristics and encoding protein and physical and chemical properties; all the amino acid sequences have a high degree of homology, containing two conservative HMG-CoA binding motifs and two NADPH binding motifs; all the amino acid sequences, containing signal peptide, are secreted proteins; they are all hydrophobic transmembrane proteins with five transmembrane domains; random coil and α-helix are the main structural elements in the HMGR polypeptide chain; all the predictions of three-dimensional structure are V- shaped; there are more closer evolution relationship between the HMGR gene from pigs and cattle.

结果表明：猪、牛和鸡HMGR基因序列特点及编码蛋白质理化性质基本相同，均属不稳定类酶蛋白；保守结构域氨基酸序列具有高度的同源性，均含有保守的2个β-羟基-β-甲基戊二酸单酰辅酶A结合基序和2个还原性烟酰胺腺嘌呤二核苷酸结合基序；均有信号肽，属分泌型蛋白质；属于跨膜的疏水性蛋白，均有5个跨膜结构域；无规则卷曲和α-螺旋是HMGR多肽链中的主要结构元件；三维结构预测都呈"V"字形；猪和牛HMGR基因的进化关系最近。

Have superconduction of Xi Menzi 1.5T machine of CT of many nuclear magnetic resonance, helix and examine of the division full automatic biochemical analyzer, full automatic corpuscular computation appearance, blood coagulates analyzer of appearance, specific protein, full automatic appearance of appraisal of immune glow appearance, bacterium large and medium-sized equipment of medical treatment instrument.

拥有西门子1.5T超导核磁共振、多排螺旋CT机以及检验科的全自动生化分析仪、全自动血球计数仪、血凝仪、特定蛋白分析仪、全自动免疫发光仪、细菌鉴定仪等大中型医疗仪器设备。

The results show that the Zn complex can be partially intercalated into the double helix of DNA due to the planarity of the benzimidazole ring and the bulky structure of the complex.

实验结果表明，由于配合物的八面体构型以及苯并咪唑环的平面性，其与DNA作用方式可能为部分插入。

In other words, Cobalt 60 nuclei and the spin direction of the beta decay of electronic exiting direction spiral form the left, not the right hand helix formation.

就是说，钴60原子核的自旋方向和它的β衰变的电子出射方向形成左手螺旋，而不形成右手螺旋。

Summary the stud pump is that one kind of one stud type is lost the stud bush that fortune pump and stud and interior surface that its major work parts are partiality spirochaetas assume the bifilar helix face .

螺杆泵是一种单螺杆式输运泵、它的主要工作部件是偏心螺旋体的螺杆和内表面呈双线螺旋面的螺杆衬套。

The stud pump is that one kind of one stud type is lost the stud bush that fortune pump and stud and interior surface that its major work parts are partiality spirochaetas assume the bifilar helix face .

概述 螺杆泵是一种单螺杆式输运泵、它的主要工作部件是偏心螺旋体的螺杆和内表面呈双线螺旋面的螺杆衬套。

The author reviews the science and technology history home and abroad,and introduces the neoteric revolution in this field,focusing on the four scientific discoveries-the Big Bang,the quark model in material structure,the plate structure,and the DNA double helix structure-and the five technological invention-nuclear technology,space technology,information technology,biotechnology and nanometer technology-in the 20th century and their academic base of theory of relativity and quantum mechanics;and the writer...

回顾了中国和世界科学技术发展的基本历程；介绍了近代的科学革命和技术革命；重点论述了20世纪科学发现和技术发明的理论基础是相对论和量子力学，以及20世纪的四大科学发现——宇宙大爆炸理论、物质结构夸克模型、大地构造板块学说和DNA双螺旋结构和五大技术发明——核技术、空天技术、信息技术、生物技术和纳米技术；展望了21世纪科技发展前途；提供了油气开发与利用的信息。

For example, the growth initial condition selects the conformation of binormal zinc oxide helix, though the normal configuration is also stable only from the aspect of energy.

例如，我们发现如果初始生长条件选择了binormal型的氧化锌纳米螺旋带，尽管从能量的角度来说，normal型的氧化锌纳米螺旋带也可以稳定存在的，那么最后生长的为binormal型的氧化锌纳米螺旋带。

If uses SLS double helix to squeeze oar machine and bosomy type or belt to wash oar machine combination to use, can raise black liquor recovery rate 90% above, carrying out a proof is feasible.

倘采用SLS型双螺旋挤浆机和鼓式或带式洗浆机组合使用，可以将黑液提取率提高到90%以上，实践证实是可行的。

Largely unstructured in solution, linear peptides fold into an amphipathic helix upon binding and insert into the target membrane, leading to breakdown of the transmembranal potential and of ion gradients, thus causing leakage of cell contents, resulting finally in cell death.

大多数的抗菌胜肽在水溶液中是呈现松散的结构，但和目标微生物作用时会褶叠形成双性螺旋的结构并插入其膜内，导致破坏膜内外的电位及离子梯度，造成细胞的泄漏，最后导致细胞死亡。

Hanna: That's over now, isn't it?

都结束了，对吗

You must be ill. You look so pale.

你一定是病了，你的脸色苍白。
