M.tuberculosis Topo I
Mycobacterium tuberculosis topoisomerase I is a bacterial type I topoisomerase which can relax supercoiled DNA. It is a potential target for antibacterial drugs and can be used for screening potential novel antibacterial compounds. It is prepared by overexpressing the protein in E. coli and then purified by chromatography.
It is supplied in Dilution Buffer. Store at -80 °C.
The enzyme is supplied with Assay Buffer (5X concentration) and Dilution Buffer (1X) which are also available separately. 1 U of topo I will relax 0.5 µg of supercoiled pBR322 DNA in 30 minutes at 37 °C.
See technical documents below for more detailed information and lot specific activities.

酶只是催化剂,其本身无法直接氧化它。
酶是具有生物催化功能的生物大分子,即生物催化剂,它能够加快生化反应的速度,但是不改变反应的方向和产物。其只能用于改变各类生化反应的速度,但并不是生化反应本身。只是催化剂的一种。
所以NADPH氧化酶只是促进了NADPH的氧化过程,无法直接氧化NADPH。
入院10天,伴有肩部肌肉刺痛,已有好转,但今天的肝功能常规检查,转氨酶突然从140多升到310多,入院一直有互肝措施,静脉输液。无不良饮食习惯。有慢性浅表性胃炎病史。问,转氨酶突然升高的原因?各项肝炎检查无问题,ct x 光无问题
--精神压力 - 身体在承受精神压力下,会消耗更多的辅酶Q10。
--环境污染和毒素侵害 - 导致辅酶Q10的消耗速度加快。
--精神压力 - 身体在承受精神压力下,会消耗更多的辅酶Q10。
--环境污染和毒素侵害 - 导致辅酶Q10的消耗速度加快。
--吸烟 - 即使是二手烟也会造成体内的辅酶Q10快速耗尽。
--运动 – 常做运动能使身体保持良好状况,但同时身体也会产生自由基。所以我们的身体需要抗氧化剂如辅酶Q10,来抑制自由基的侵害。
--食用医生常开的降胆固醇药物。
--某些食物(包括动物内脏、牛肉、鱼肉和果仁)虽含有辅酶Q10,但是,我们得大量进食这些食物才能从中摄取足够的份量。
*辅酶Q10能在人体内产生效用
大部分细胞都含有介于500至2,000的粒线体。这些粒线体犹如小小的“能量工厂”,把我们所吃的食物转化为能量。研究显示,人体血液中的辅酶Q10水平一旦减少25%,体内的主要器官(尤其是心脏)就会因为能量不足而无法维持最佳运作状态。
#重拾无穷精力和干劲
人体细胞需要能量以建构和修复组织、清除危害健康及致病的细胞废物或毒素、抵御细菌和病毒感染,以及调节器官机能。辅酶Q10是促进能量生产的要素,缺乏辅酶Q10,体内的能量生产速度就会减缓。
#心脏更强健
心肌需依赖辅酶Q10以生产足够的能量。由于人体内的辅酶Q10量会随着年龄的增长而持续降低,当您年逾50岁时,您的心脏就会因为匮乏能量而出现状况 , 无法正常的把足够的氧份和重要的营养素输送至身体各个器官和组织。如此一来,细胞就无法生产足够的能量好让身体保持活力,随之出现疲倦和健康衰退的现象。因此,要是您经常感觉疲惫,很可能是您的心脏在渴求辅酶Q10。
根据德克萨斯大学的研究显示,心脏病患者体内的辅酶Q10水平往往低于没有心脏病的人士。超过75%的心脏病患者在服用辅酶Q10作治疗之后,病情显著改善。辅酶Q10不仅能为心肌生产能量,也能稳定心脏脉冲和心脏导电系统,减低罹患心律异常或心悸问题的风险。
#血压更健全
心脏一旦能生产更多能量,便能发挥更强劲的脉动能力。如此一来,体内的血液循环便有所改善。由于血液更流通,血管更具灵活弹性(辅酶Q10对血管产生抗老化作用所致),血压自然也就更健全。不过,血压的降减现象须在服用辅酶Q10至十二个星期才可见效。高血压是无声的杀手,足以造成中风,心脏病发作、心脏和肾脏衰竭。
更健全的胆固醇水平
辅酶Q10 是一种强效的抗氧化剂,能抗防LDL“不良”胆固醇的氧化,使人体内的胆固醇保持于健康水平。LDL 的氧化会造成不良胆固醇更易粘附在血管壁,导致血管阻塞。这就是为何没有高胆固醇的人士也会出现血管阻塞之故。辅酶Q10的抗氧化作用比维他命E更胜一筹。更妙的是,辅酶Q10还能为体内“用过的”维他命E再充电,好让维他命E恢复十足劲力。维他命E与辅酶Q10能结合一股超强防护力量,预防心血管疾病。
#增进脑力
如果您的头脑不如以往般的敏锐,或者常觉得精神疲倦,难以清晰地思考,这可能只因您体内缺乏辅酶Q10之故。您的脑部细胞需要大量能量以维持最佳运作状态。只要这些细胞能取得无穷的能量供应,您必能感觉头脑敏捷,思维清晰。
#增强身体的抵抗力
辅酶Q10 能增强人体免疫细胞,使它们更有活力,更能抵抗疾病之侵。免疫细胞一旦获得更多能量,就能更强力地保护人体及清除微生物,毒素和致病的突变细胞。辅酶Q10 也能增加免疫细胞数量,为人体提供更周全保护。
#容颜更显,青春焕发
氧化所带来的破坏力是导致皮肤老化迹象的罪魁祸首,也是引发种种皮肤炎(包括皮肤发疹和湿疹)的祸根。自由基侵袭皮肤内的胶原蛋白和弹性纤维,造成皮肤失去弹性,随之变得松弛及出现皱纹。自由基也导致肌肤出现色素斑和色泽不均匀。辅酶Q10 是一种强效抗氧化剂,能抑制自由基侵害,使肌肤更显光泽,容光焕发及青春常驻。
#辅酶Q10 的其它功效
帮助糖尿病患者调节血糖量,并且有助于预防最常见于糖尿病患者的多种心脏问题。
减轻牙周问题,例如牙龈退缩,牙齿松动,牙龈肿胀。
舒解气短和心悸问题。
并非所有的辅酶Q10营养品都一样有效果!
市面上贩售的大多数辅酶Q10营养品,不容易被人体吸收,而这些未经吸收的营养素,不管品质有多好,对身体根本毫无益处,只是浪费金钱!
辅酶Q10之所以难以被人体吸收,原因在于辅酶Q10是一个非水溶性及只有部分可在脂质中溶解的大粒子。要确认您所食用的辅酶Q10是否能溶解及被您的身体所吸收,可将辅酶Q10胶囊内容物倒入一杯清水(若是凝胶丸,可把它切开)。如发觉即使加以搅拌之后仍无法跟水溶和在一起,表示就算您服用此辅酶Q10,也难以被您的身体所吸收利用, 而造成浪
