查询词典 adenine

By comparing with known compound A2'P 5'A,it was shown that two ribose rings of a and b adopt predominantly S conformation at 18℃, but with elevation of temperature, the N conformation of some ribose ring increaed: the torsional angles e' and β of the phosphate backbone were estimated to have a change of +2° and ±12°respectively; two ribose rings of both A2'P(CH3)5'A and were partially overlapped and the degree of overlapping of was smaller than that of the : with increasing of temperature, the adenine moiety of A2'P(CH3)5'A showed a stronger tendency to unstack than A2'P(CH3)5'A .

它们与A2′P5′A相比发现：(1)在18℃时两个核糖环是S型构象占主要成分，但随温度升高有的核糖环趋向于转化成N型构象；(2)磷酸骨架的扭角ε′和β分别改变±2°及±12°；(3)A2′P(CH_3)5′A和的两个核糖环均属部分重叠，并且前者的重叠程度小于后者；(4)随着温度升高，A2′P(CH_3)5′A比A2′P(CH_3)5′A有着更强的去堆积效应。

A form of post-transcriptional modification to mRNA in eukaryotes in which adenine is deaminated to form inosine, an unusual base.

真核生物中对mRNA进行转录后修饰的一种形式，修饰时将腺嘌呤脱氨基形成次黄苷，次黄苷是一种非普通碱基。

A I editing A form of post-transcriptional modification to mRNA in eukaryotes in which adenine is deaminated to form inosine, an unusual base.

A I 编辑真核生物中对 mRNA 进行转录后修饰的一种形式，修饰时将腺嘌呤脱氨基形成次黄苷，次黄苷是一种非普通碱基。

In the dehydrogenating process,the anionic A-T fragmentgradually changes its electronic configuration fromπ~* toσ~* state,like the singlebases adenine and thymine.

在脱氢过程中，阴离子A-T的碎片会逐渐改变它的低能电子组态，从π~*态转变到σ~*态，这种变化跟在单个碱基腺嘌呤和胸腺嘧啶的情况相似。

DNA methylating inhibitor makes the transfer of the methyl group to adenine or cytosine impossible,thus the reaction of DNA methylation is inhibited,the genomic methylation level is decreased.

DNA甲基化抑制剂使甲基基团不能转移到腺嘌呤或胞嘧啶，导致DNA甲基化反应受阻，从而使基因组甲基化水平降低。

The shorter variant mHemk2 is 1696 bp in length encoding a putative mouse protein of 14.7 kDa, consisting of 138 amino acid residues.In protein data bank annotations, Hemk has previously been classed among methyltransferases methylating N6-adenine or N4-cytidine in DNA because of the presence of S-adenosyl-L-methionine binding motif and of an NPPY motif in the protein.

在蛋白数据库的注释中，由于在Hemk蛋白中存在S-腺苷-L-甲硫氨酸结合基序和一个NPPY基序，因此，在蛋白库的说明中已经将Hemk蛋白归类于能甲基化DNA中N6-腺嘌呤或N4-胞嘧啶的甲基转移酶。

A glassy carbon electrode was modified by pipetting a aliquot solution of the material onto the electrode surface to prepare electrocatalytic sensor of β-nicotinamide adenine dinucleotide.

SCE左右出现一氧化峰，与未修饰的玻碳电极相比，该修饰电极明显降低了NADH的氧化峰电位，消除了反应中间产物对电极表面的污染问题。

In this thesis, shikonin, cryptotanshinone and 5-fluorouracil (5-FU) were selected as the objects for several aspect studies: In Chaper 2, the electrochemical behavior of shikonin was investigated by cyclic voltammetry, linear sweep voltammetry, chronocoulometry and bulk electrolysis with coulometry on a glassy carbon electrode. Triple strand DNA modified electrode was preparated and used to investigate the interaction of shikonin with DNA. It was found that it is hydroquinone of shikonin to embed in DNA and interacted with guanine and adenine of DNA.

本论文以紫草素、隐丹参酮和5-氟尿嘧啶三种抗癌药物为研究对象，做了以下几个方面的工作：在论文的第二章，我们研究了紫草素的电化学基本性质，初步探讨了三链DNA 修饰电极的制备，并利用该修饰电极研究紫草素与DNA 的相互作用，得出主要是紫草素的氢醌与DNA 的G、A 碱基间发生嵌插作用的结论。

MethodsSixty Wistar rats were divided into 2 groups randomly: normol group(n=12), and model group(n=48).The model rats were fed with high fat-sugar diet for 6 weeks, then fed with adenine(100 mg·kg-1·d-1) and ethambutol(250 mg·kg-1·d-1) for 2 weeks to induce the IR and hyperuricemia model.

方法选用 60只成年Wistar雄性大鼠，随机分成正常对照组（12只）和模型组（48只），模型组给予高脂高糖饲料餵养6周，6周后再用腺嘌呤〔100 mg/kg·d）〕加乙胺丁醇〔250 mg/〕灌胃2周，造成胰岛素抵抗并高尿酸血症的大鼠模型。
