Objective: To explore the relationship between catechol-O-methyltrans -ferasegene Val108/158Met polymorphism and tardive dyskinesia in Chinese Han people.

目的：探讨中国汉族人口中儿茶酚胺氧位甲基转移酶基因Val108/158Met多态性与迟发性运动障碍的关系。

Ferruginous smectite had larger oxidative and reductive power due to the existence of Fe(superscript 2+/3+) in the octahedral layer, and hence its catalysis for catechol was much more obvious than other clay minerals used.

多铁蒙特石由於其八面体层中的Fe(上标 2+/3+)具有较大的氧化还原效能，故在邻苯二酚的催化能力上较其它两种黏土矿物明显。

The apparent Km values with guaiacol, catechol and pyrogallol as substrates were 2.75, 12.4 and 12.8mmol/L at 25℃ and pH 7.0, respectively.

该酶在25℃和0.05mol/L磷酸缓衝液(pH7.0)条件下对愈创木酚、邻苯二酚和没食子酸的Km分别是2.75、12.4和12.8mmol/L。

The effect of physicochemical factors on phenoloxidase activity of hemocyanin from Haliotis diversicolor was studied with catechol as substrate.

以邻苯二酚为底物研究部分理化因子对杂色鲍血蓝蛋白酚氧化酶活性的影响。

And 1. 0M respectively. BYS-1 could use anline, phenol and salicylic acid as substrate to support growth, but could not use catechol and quinol, it could use benzoic acid poorly.

The protein had the specificity on substrate recognition, which could decompose 3,4-dihydroxybenzoic acid to catechol but not 2,4-dihydroxy- benzoic acid to resorcin. The ligand at C-3 site of benzene ring had no effect on enzyme activity.

蛋白质还具有底物识别的特异性，能够催化3，4-二羟基苯甲酸转化为邻苯二酚，而不能催化2，4-二羟基苯甲酸转化为间苯二酚，这表明苯环上3'位的配基对酶活无影响。

Analysis of the treated aqueous solution was conducted with GC-MS,and the main intermediates during phenol degradation were isobutyric acid,malonic acid,benzoquinone,butenoic acid,oxalic acid,maleic acid,succinic acid,hydroquinone,catechol and resorcin.

利用GC-MS分析了苯酚降解主要中间产物为异丁酸、丙二酸、对苯醌、丁烯酸、乙二酸、顺丁烯二酸、丁二酸、邻苯二酚、对苯二酚及间苯二酚等，并据此推测了苯酚电催化氧化的可能反应途径。
