乙醛酶

The preliminary stiochiometric analysis showed that when the enzyme metabolized EDDA, two acetyl groups were removed and ethylenediamine and two glyoxylates were produced in the presence of oxygen.

然后对该酶促反应进行了定量分析：结果显示在IDA氧化酶的作用下每代谢一分子的EDDA将生成二分子的乙醛酸及一分子的乙二胺，同时也检测到过氧化氢的生成。

Sequencing revealed that the most common genes appearedin the library is photorespiratory-related genes, such as ribulose bisphosphate carboxylase, Rubisco activase, glyoxylate aminotransferase, glutamine synthetase,glyceraldehyde dehydrogenase, ferredoxin, transport protein, etc.

测序之后发现最为显著的是一些光呼吸相关的基因如核酮糖-1，5-二磷酸羧化／加氧酶、Rubisco激活酶、乙醛酸转氨酶、谷氨酸转氨酶、甘油醛脱氢酶、铁氧还原蛋白和转运蛋白等。

Its substrate is glycolate produced in C3 plants by the oxidation of ribulose bisphosphate to glycerate 3-phosphate and phosphoglycolic acid.

在过氧化物酶体中，乙醇酸在乙醇酸氧化酶作用下，被氧化为乙醛酸和过氧化氢。

Purified GO could oxidize both glycolate and glyoxylate, and both activities highly depended on FMN. The activity of glyoxylate oxidation was weaker than that of glycolate. During purification or storage of purified GO, the ratio of glycolate to glyoxylate oxidation was progressively enhanced.

纯化的菜心叶片乙醇酸氧化酶对乙醇酸和乙醛酸均有氧化活性，且两者都强烈依赖于FMN，但对乙醛酸的氧化能力相对较弱；在酶的纯化及纯化酶的贮存过程中其两催化活性的比值均呈逐渐升高的趋势。

The accumulating plant physiological information shows that plant hormones, especially such as IAA, play very important roles during head leaf development, The experiment that transfering aux1 and aux2 genes (respectively encode trytophan monooxygenase and indoleacetamide hydrolase, which are needed for two-step synthesis of IAA) into Chinese cabbage-pe-tsai proves such supposal.

现有的植物生理学研究认为，植物激素特别是IAA在叶片的弯曲上起重要作用，将IAA合成中的色胺酸加氧酶基因aux1和吲哚乙醛还原酶基因aux2转入大白菜中的实验也支持了生理学的这一推测。

It shown that PDC does not only catalyze the production of acetaldehyde (PDC's main activity), but also catalyzes an aldoltype condensation reaction in which the hydroxyethyl-ThDP intermediate of enzyme is condensed with a second acetaldehyde to form acetoin.

在研究中发现PDC不仅能催化产生乙醛，还具有醛连接酶的活性。即将二个乙醛分子缩合成3-羟基丁酮，尽管这个活性比产生乙醛的活性低得多。

The results showed that ascorbic acid oxidase activity in the flesh of 'brumal Jujube' became significantly higher than in pericarp with the development of maturity; but these activities of peroxidase , Polyphenoloxidase and phenylalanine ammonia-lyase in flesh were lower than in pericarp . During the development from green to half-red then to red, the lignin and fibre contents in pericarp gradually increased higher than in flesh; ethanol content also increased , acetaldehyde content reached to a peak during the red maturity stage and then declined.

随着贮期的延长，冬枣果肉中乙醇和乙醛含量增加，乙醇发酵关键酶的活性逐渐升高；气调贮藏延缓了果实中乙醇和乙醛的积累，抑制了PDC和ADH的活性，显著提高了果实的贮藏品质；说明气调贮藏延缓了果实的乙醇积累；但CA_1比CA_2促进果实乙醇积累的作用较明显，表明冬枣对高浓度CO_2较敏感，这可能是枣果实不耐高CO_2的原因之一。

BADH cDNA (1785bp) included a 63 bp 5 "UTR, a 219 bp 3 "UTR and a 1503 bp ORF encoding a 500-amino-acid polypeptide which showed closely similar sequence identity to BADH from Chenopodiaceae.

将BADH的编码区推测的氨基酸在GenBank中进行分析，能找到磷酸果糖激酶、乙醛脱氢酶家族，谷胺酰磷酸还原酶等的保守区域。

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。
