The results show that all the hmgr genes from pigs, cattle and chickens are astable enzyme proteins with the same gene sequence characteristics and encoding protein and physical and chemical properties; all the amino acid sequences have a high degree of homology, containing two conservative HMG-CoA binding motifs and two NADPH binding motifs; all the amino acid sequences, containing signal peptide, are secreted proteins; they are all hydrophobic transmembrane proteins with five transmembrane domains; random coil and α-helix are the main structural elements in the HMGR polypeptide chain; all the predictions of three-dimensional structure are V- shaped; there are more closer evolution relationship between the HMGR gene from pigs and cattle.

结果表明：猪、牛和鸡HMGR基因序列特点及编码蛋白质理化性质基本相同，均属不稳定类酶蛋白；保守结构域氨基酸序列具有高度的同源性，均含有保守的2个β-羟基-β-甲基戊二酸单酰辅酶A结合基序和2个还原性烟酰胺腺嘌呤二核苷酸结合基序；均有信号肽，属分泌型蛋白质；属于跨膜的疏水性蛋白，均有5个跨膜结构域；无规则卷曲和α-螺旋是HMGR多肽链中的主要结构元件；三维结构预测都呈"V"字形；猪和牛HMGR基因的进化关系最近。

Copper is one of the essential microelements for plants. But in recent years, the abuse of copper bactericide and industrial pollution has led to the increase of copper content in environment such as in soil.

铜是一种高等植物生长发育过程中必需的重要微量营养元素，是许多胞内酶所必需的组分或辅酶，它参与很多生理代谢过程，对作物的发育、品质、产量等有重要的影响。

Carbonyl reductase is a monomeric oxidoreductase that catalyzes the NADPHdependant reduction of a variety of quinones, ketones, and aldehydes. It is widely distributed in the cytoplasm of various tissues of mammalian and non-mammalian species, and is involved in detoxification, physical regulation, as well as in drug metabolism.

羰基还原酶是一类依赖于辅酶NADPH催化各种醌、酮和醛等物质还原的单体氧化还原酶，它们广泛分布于哺乳动物和非哺乳动物各种组织的细胞质中，具有解毒、生理调节和药物代谢等重要功能。

The identity of the gene encoding the mitochondrial K-activated acetaldehyde dehydrogenase K(+-ACDH of Saccharomyces cerevisiae has been confirmed. The gene is situated on the right arm of chromosome XV, bears the systematic name YOR374w and the deduced product shows significant homology to other members of the S.

中文摘要酵母菌醛类去氢酶4（YOR374w）是一种位在粒线体内的去氢酶，需要钾离子的活化，以及NAD+或NADP+当辅酶，在乙醇的代谢途径扮演很重要的角色，尤其是以乙醇当碳源的环境下。
