查询词典 binding over

Esculetin had the highest affinity toward the binding site of XO, and this was due to hydrogen bonding interactions. The hydroxyl group at C-6 formed hydrogen bonds with the carboxyl group Glu802 that played critical role on XO binding.

在8种香豆素衍生物中发现esculetin与黄嘌呤氧化酶的亲和力最高，因为在esculetin的结构上，C-6的OH基团可与麸胺酸802的COOH基团形成氢键，此键结对於抑制黄嘌伶氧化酶活性是很重要的，因而增加了两者结合的稳定性。

As well using flameless atomic absorption spectophotometer toanalyse the amount of platinum binding to DNA,we can fand that after 1hour at 37℃ the amount of platinum binding to DNA for BGC-823 acted byCDDP 20ug/ml in hypotonic solution was 30.1±6.2ng/mg·DNA,whilethe isotonic groups were 6.4±1.5ng/mg·DNA.

采用非火焰原子吸收光谱法检测DNA结合铂含量发现，BGC-823经20μg／ml CDDP，37℃作用1小时，低渗给药组DNA结合铂含量为30.1±6.2ng／mg·DNA，等渗给药组DNA结合铂含量为6.4±1.5ng／mg·DNA，两者差异显著(P＜0.05)，该结果表明低渗溶液能显著增强CDDP与其作用靶点—DNA的交联。

However, the binding patterns between the HU-induced and uninduced HEL cells were different. The data in Southwestern-blot analysis showed that the molecular weights of the GATA factors binding to the HS2core DNA sequence were 43kd and 47kd respectively.

反义寡核苷酸技术及RT-PCR的结果表明，GATA-1的反义核苷酸抑制了羟基脲诱导的β-珠蛋白基因的表达，进一步证明了GATA-1因子在羟基脲诱导的HEL细胞分化过程中是不可缺少的促进因素。

Biotinylated lectins:UEA-Ⅰ, RCA-Ⅰ, DBA, PSA, PNA, BSL, LCA, WGA, ConA AND SBA were used as probes to identify lectin binding sites and to determine if lectin binding patterns change with age in the developing of human fetal esopha geal epithelium (8W, 14W, 20W, 28W and 32W).

采用十种生物素化凝集素UEA-I、DBA、PSA、B SL、PNA、LCA、RCA-I、SBA、ConA及WGA分别对8W、14W、20W 28W及32W的人胎儿食管上皮进行研究，以确定胎儿食管上皮在发育过程中凝集素的结合位点以及结合方式随年龄的变化。

METHODS: Cytometry and soft agar were employed in observing the biological characters of MEC-1 and Mc3 cell strain. The expressions of the two sub-types of MEC-1 and Mc3 cell strain, SSTR1 and SSTR2, were detected by hybridization in situ. The condition of the binding between MEC-1, Mc3 and 125I-RC-160 was analyzed by radioactive genin binding analysis.

采用细胞计数法、软琼脂法等观察MEC-1及Mc3细胞株生物学特性；以原位杂交法检测MEC-1，Mc3细胞株SSTR1及SSTR2两种亚型的表达情况；以放射配基结合分析法分析MEC-1，Mc3细胞与125I-RC-60的结合情况。

The results showed that though apoHb could be reconstituted with all FePs, it showed different functions. Binding of apoHb with hemin can enhance the heterolytic cleavage of O-O bond of H〓O〓, but inhibiting the cleavage when FeTCPP and FeTPPS〓 were used instead of hemin. The binding of apoHb with FeTTMAPP showed negligible influence on the cleavage of O-O bond in H〓O〓.

结果表明，虽然具有阴离子基团的FeTCPP和FeTPPS〓能够在天然血红蛋白中辅基位置的附近与脱辅基血红蛋白结合，但是由于结构上与天然辅基的差别，使得血红素蛋白中相应的氨基酸残基不能起到有效的作用，因此不但不能提高反而抑制了其过氧化物酶活性；而对于具有阳离子基团的FeTTMAPP，脱辅基血红蛋白对其活性没有明显的影响。

For example the whole book visions of luxury and bookbiding or heterotype or sewing binding or binding hardcover and air back processing without plugging a soft cloth hardcover, etc.

例如整书装订方式出现的豪华装、异型装、无线胶订或锁线胶订精装、空背加工不黏堵布的软精装等。

Results Intercalative binding and groove binding coexisted between yeast dsDNA and GM.

These results indicated that palmatine had one common binding site on the immobilizedβ_2-AR column,the association constant was 2.93×10~4 L/mol at pH 7.2 and 25℃,while jatrorrhizine had two bingding sites,the association constants at these two sites were 1.93×10~4 and 1.56×10~5 L/mol,respectively.And the molar ratio of weak bingding sites to strong binding sites was 93:7.Palmatine and jatrorrhizine had competed for low-affinity site in immobilizedβ_2-AR.

Studies of the binding of metal to calmodulin and the subsequent binding of metal-calmodulin complexes to the target protein/peptide revealed that the La-content calmodulin complexes to its target exhibit similar affinity with the Ca-calmodulin complexes.However, there were substle differences in protein conformation as well as the kinetical properties between the two kinds of metal-calmodulin complexes, suggesting Ln could produce cellular effects via the Ca/calmodulin signaling systems.
