磷酸酶

For obtaining maximal yield of hydrogen how to make glycolysis to produce large amount of NADH at TCA cycle and also to reoxidize FADH2 through electron transport chain by oxygen or other electron acceptors were chief introduced .

文中着重介绍了如何通过 TCA cycle使葡萄糖酵解产生大量的 NADH(还原型二磷酸吡啶核苷酸)，抑制 NADH脱氢酶络合物的电子迁移链而得到最高氢气产量。

Then a high-efficiency genetic transformation system was established, by which two transgenic Roselle cell lines that stably express the activity of neomycin phosphotransferase Ⅱ were obtained.

利用这一转化体系获得了2个稳定表达新霉素磷酸转移酶活性的玫瑰茄转化细胞系。

Nucleotide-induced eNOS phosphorylation and activity were inhibited by BAPTA-AM (an intracellular free calcium chelator), rottlerin, and protein kinase C siRNA.

BAPTA-AM（一种细胞内游离钙螯合剂），rottlerin和蛋白激酶C siRNA抑制核苷酸介导的内皮型一氧化氮合酶磷酸化和活化。

Sequence analysis revealed the presence of a 735 bp open reading frame encoding 244 amino acids protein, which shares 32.9 %~49.2% amino acids sequence similarity to PRAI proteins from other species of Saccharomycetales.

序列分析显示，该基因编码区全长735 bp，编码的磷酸核糖氨基苯甲酸同分异构酶氨基酸序列与其他酵母来源的PRAI蛋白同源性在32.9%~49.2%之间。

Moreover, the researchers believe that in soybean, cotton, Brassica and Solanaceae plants and the development of forest tree species, AtWBC19 mycophenolate may be an alternative new phosphotransferase.

而且，研究人员认为在大豆、棉花、芸苔和茄科植物及森林树种的开发中，AtWBC19也许可替代新霉磷酸转移酶。

The binding interaction of DNA with the di-iron complex 〓, designed as a model for the di-iron active site in mammalian purple acid phosphatase , are examined firstly and spectroscopically.

对所有研究的含有双核铁、双核锌及双核铜的配合物促进DNA双链水解断裂的反应性进行比较，我们发现要有效地水解断裂DNA双链，对DNA骨架的磷酸基氧原子有一定配位作用的双核金属离子是必要的，因为两个金属离子间存在协同作用，这与有关的天然酶类似。

In conclusion , ERK and telomerase serve a function to some extent in drug resistance of leukemia and ovariancarcinoma cells. The inhibition of ERK signal transduction pathways led to reduction of phosphorylated ERK1 and ERK2protein expression level , and successionally down2regulated the telomerase activity.

通过阻抑ERK通路，降低磷酸化ERK1/ 2蛋白表达水平，进而下调端粒酶活性，可以达到增强白血病和卵巢癌耐药细胞对HRT 或DDP 敏感性的目的。

Motilin and gastrin induced contraction of isolated gastric smooth muscle cells in a dose-dependent manner.(2) Motilin- and gastrin-induced antral smooth muscle cell contraction was inhibited by antibodies against Gαi-3. Motilin and gastrin caused an increase of Guanosine-5′-(3-［35S］thio)triphosphate(［35S］GTPγS) binding of Gαi-3.(3) Contraction of antral muscle cells induced by motilin and gastrin was inhibited by the phospholipase C inhibitor U-73122 and the IP3 receptor antagonist heparin.

结果显示：(1)胃动素和胃泌素对胃窦平滑肌细胞均有收缩作用；(2) Gαi-3抗体可抑制胃动素和胃泌素加强胃窦平滑肌细胞的收缩，胃动素、胃泌素明显增加Gαi-3抗体与［35S］GTPγS的结合；(3)磷脂酶C抑制剂U-73122、三磷酸肌醇受体拮抗剂肝素可抑制胃动素和胃泌素引起的胃窦平滑肌细胞的收缩。

In contrast to lung sequestration of neutrophil count,there were no transpulmonary gradient of MBE between left and right atrium after aortic declamping.

MBE或MBE总活性与术后炎性反应标记物如C反应蛋白及组织功能标记物如乳酸、肌酸磷酸激酶、丙氨酸氨基转移酶之间均无相关关系。

It will also damage the biomembrane, for example, the damage ofmitochondria will decrease the tricarboxylic acid cycle and oxidative phosphorylation,so the synthesis of ATP will be decresed.

如造成线粒体膜损伤，可减少三羧酸循环和氧化磷酸化，ATP合成障碍；对膜蛋白如酶、受体、离子通道等造成损伤，降低运动能力。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
