During the stimulation of pkc , it is very important that plcr is activated first . sh2a protein expressed in the transfected cells may cause an inhibitory competition with plcr for the sh2 binding site of the up 二3h基因编码蛋白的亚细胞定位我们通过pso盯11prediction ( predictionofp telnlocallzatlonsites )软件,对sh基因的亚细胞定位进行了预测。
Predicted tertiary structure showed that thl2 protein possessed a domain , and the srk - binding site cppc is located in tertiary structure surface , which provided the spacial foundation for thl2 binding srk kinase 预测的thl2蛋白质高级结构中有一个结构,并且其与srk结合的活性位点cppc位于蛋白质的表面,这为thl2蛋白与srk激酶结合提供了空间上的基础。
Both of them are localized within the endoplasmic reticulum ( er ) and possess atp - binding sites . envidence has shown that grps function as molecular chaperones by assisting in the proper folding and assembly of proteins within the er 同时他们又是分布在内质网( endoplasmicreticulumer )腔内的分子伴侣,具有弱的atp酶活性,与atp结合后可以协助新生蛋白质的转位、折叠以及寡聚蛋白的组装。
Using a computer program , a peptide was deduced from residues 256 - 265 of human fas ligand , based on the hypothesis that it should contain a specific binding site to the corresponding fas . this short peptide and fas contain 70 % of sense - antisense pairs 本研究依据ahbs理论,应用自行编写的软件,在fasl分子中寻找到与fas相应的反义多肽最为接近的十肽结构即fasl _ ( 256 - 265 ) (匹配度为70 ) 。
Like calmodulin and troponin c , caltractin contains four potential calcium - binding sites of predicted helix - loop - helix or ef - hand structure . with the development of technology in biology , more and more academicians study questions for discussion by mutating genes in organisms 中心蛋白的结构类似于钙调蛋白、肌钙蛋白c的结构,含有四个ef - hand ( helix - loop - helix )结构,即四个钙结合位点。
This n2 and h + binding and reduced model also developed our early proposed two - site h2 evolution model for nitrogenase : site i , n2 - dependent h2 evolution site , is provided by the central six - fe region of femoco , which is also provided the n2 , c2h2 , co binding site 结合的高柠橡酸传入,其反应式为: zh + + 2e ’ , hz ,此反应不受co抑制; 。心inl90一高柠稼酸一m 。是一条通向femoco的重要的电子传递途径。
Sequence analysis showed highly similarity to other plants such as narcissus pseudonarcissus . , and they all possess a short highly conserved n - terminal sequence encoding a dinucleotide cofactor binding site . thus it is a new member of phytoene desaturase gene family 由此可认为该番红花八氢番茄红素脱氢酶基因在结构上与其它植物八氢番茄红素脱氢酶基因是同源的,是八氢番茄红素脱氢酶基因家族中的一个新成员。
Molecular imprinting is a rapidly expanding technique to create molecularly imprinted polymers ( mips ) with high selectivity . this technique is a powerful method for preparing the tailor - made binding sites based on the molecular structure and functional group of the analyte 通过分子印记技术可以获得稳定的合成聚合物? ?分子印记聚合物( mip ) ,它的识别部位可根据待测分子的结构和官能团来进行“量身”定做,因此具有选择分子识别的性质。
Inhibition of ros activity by catalase , n - acetylcysteine or diphenylene iodonium abrogated low k + - induced increases in the - subunit promoter activity , 1 - and 1 - subunit polypeptide abundance , and binding sites of na , k - atpase , indicating the role of ros in the effect of low k + 抗氧化剂nac与catalase 、 dpi能抑制低钾的作用。提示ros产生与细胞膜nadph氧化酶有关。进一步研究表明, h2o2 ,而非超氧根离子参与了低钾对钠钾atp酶的调节。
It was devoted that class ii promoter was stimulated by ie180 . there is not tata box on the upstream of the promoter , but there are binding sites of protein in the upstream of the promoter . david and his company identified ie gene in the human cytomegalovirus virus dna segment 目前国内外没有关于野生型的ie180或其突变体对sv40和cmv启动子调控作用的报导,此研究可为ie180基因缺失突变体,在人的巨噬细胞病毒和猴空泡病毒40控制方面的应用提供理论依据。
In biochemistry, a binding site is a region on a protein, DNA, or RNA to which specific other molecules and ions?in this context collectively called ligands?form a chemical bond.
