磷酸化酶

It has unique substrate specificity, and required minimal sugar chain in the degradation direction and synthesis direction of trisaccharide and disaccharide separately.

该酶具有独特的底物特异性，其降解方向和合成方向所需的最小糖链长度分别为三糖和二糖，均比普通的葡聚糖磷酸化酶少一个糖基以上。

This process was studied by following the substrate reaction of GPa in this paper.

Meanwhile, ABA inhibited the activities of phospho-glucose isomerase and invertase, increased the activities of phospho glucose mutase and starch phosphorylase, indicating that ABA was the most effective factor in saccharide metabolism and to the related enzyme activities on the 1st to 7th days after treatments.

推测非还原糖含量的升高可能是ABA促进其积累和抑制转化酶活性所致，淀粉含量升高的原因可能是ABA增强了淀粉磷酸化酶的活性，果糖与葡萄糖比值的降低可能是由于ABA对PGI活性抑制和对PGM活性促进的双重影响。

AIM: To investigate the expressions of methylthioadenosine phosphorylase and ornithine decarboxylase in human ovarian cancer.

So, is the cAMP protein kinase and phosphorylase a key enzyme system .

所以蛋白激酶是cAMP与磷酸化酶系统中一个关键的酶。

The Klason lignin level of anti-4CL-transformed tobacco was much lower than that of the control. The cellulose content increased in transgenic tobacco with UGPA constructs.We also obtain transgenic tobacco transformed with Acetobacter xylinum UGPase gene.

研究了木醋酸菌来源的UGPase基因与植物来源的UGPA基因在转基因烟草中的表达，测定了两种转基因烟草的尿苷二磷酸葡萄糖焦磷酸化酶的活性、木质素含量和纤维素含量。

Enzymes of glycolysis (hexokinase,lactate dehydrogenase,aldolase) showed low activities during overwintering when more carbon flowing into treh alose synthesis.

越冬期间体内糖原磷酸化酶活性明显地增加，糖酵解有关的酶（己糖激酶、乳酸脱氢酶和醛缩酶）活性较低，以保证更多的碳源转化成海藻糖。

Compared the lignin and cellulose level of these two kinds of transgenic tobacco, we found that the cellulose content increased and the lignin content deduced in transgenic tobacco transformed with Amorpha fruticosa UGPA constructs, both the cellulose content and the lignin content increased in transgenic tobacco transformed with Acetobacter xylinum UGPA constructs.

结果表明，两种转基因烟草的尿苷二磷酸葡萄糖焦磷酸化酶的活性均有明显提高；转紫穗槐UGPA基因的烟草纤维素含量有所提高，木质素含量略有降低，纤维素与木质素含量之大连理工大学博士学位论文比提高；而转木醋酸菌来源的UGPase基因的烟草木质素含量和纤维素含量均显著提高。

Another Amorpha fruticosa cDNA clone encoding 4-coumarate:CoA ligase (4CL), a key enzyme of phenylpropanoid metabolism related to lignin forming, was cloned ,too.A full-length UGPase cDNA was obtained.

所获得的紫穗槐尿苷二磷酸葡萄糖焦磷酸化酶基因UGPA长1832bp，其中开放阅读框1416bp，编码471个氨基酸，与其它植物的UGPase基因的序列相比有较高的同源性。

Trehalase plays an important role in glycogen accumulation in the formarion of diapaused eggs. At the beginning of diapause, glycogen phosphorylase is the key enzyme to glycogen decomposition and the formation of sorbitol and glycerol, whereas at the stage of diapause termination, NAD-sorbitol dehydrogenase is the key enzyme to sorbitol decomposition and glycogen re-synthesis.

在滞育卵形成过程中，海藻糖酶对糖原的积累起着重要的作用；在滞育开始时，糖原的分解与山梨醇、甘油的形成，糖原磷酸化酶是关键酶；在滞育解除时，山梨醇的分解与糖原的再生成时山梨醇脱氢酶(NAD-sorbito1 dehydrogenase)是关键酶。

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。
