服务介绍 酵母锌离子转运活性检测试剂盒是用于检测蛋白是否具有锌离子转运活性。通常采用△zrc1 cot1酿酒酵母菌株,△zrc1 cot1酿酒酵母菌株为Zn2+/锌离子缺陷型菌株,其缺失了△zrc1和 cot1,丧失了转运Zn2+的能力。△zrc1 cot1多用于Zn2+转运蛋白的鉴定试验中,该菌株对Zn2+特别敏感,在含有1000uM ZnCl2的培养基上生长,其生长受到明显抑制。 服务优势 ▶可检测蛋白是否具有锌离子吸收转运活性,简单高效。 ▶本司有锌离子转运活性检测所需的全部试剂、菌株和载体。 服务流程
文案展示 Identification and characterization of MtMTP1, a Zn transporter of CDF family,in the Medicago truncatula 期刊:Plant Physiology and Biochemistry
Zn resistance of the yeast zrc1 cot1 double mutant expressing MtMTP1. A, The yeast zrc1 cot1 double mutant CM137 was transformed with pYES2-MtMTP1. CM137 is a negative control, and CM100 (wild-type) is a positive control. Serially diluted yeast cultures were spotted on SC (2% galactose-ura) plates with 500 mM ZnCl2 (b) or no ZnCl2 (a). Plates were incubated for 3 days at 30 C. B, Zinc tolerance of yeast cells in liquid culture. CM137 transformed with MtMTP1 (triangles) or empty vector (squares), and CM100 (diamonds) were incubated in liquid SC (2% galactose-ura) medium supplemented with indicated concentration of ZnCl2. The density of culture was measured after culturing for 24 h at 30 C with shaking at 150 rpm. The OD600 of the initial density of cell cultures was 0.01. 适用领域 ▶锌转运蛋白功能鉴定:鉴定植物、微生物、动物来源的候选锌转运蛋白基因的体内转运功能,明确目标基因是否具备介导锌离子跨膜吸收的核心活性,是基因功能验证的关键技术手段。 ▶植物逆境生理研究:解析作物在缺锌、重金属胁迫等逆境下,锌转运蛋白在维持细胞内锌离子稳态中的作用;筛选耐低锌或锌高效利用的作物基因,为养分高效利用育种提供靶点。 ▶微生物锌代谢机制解析:研究细菌、真菌等微生物的锌转运系统,明确锌转运蛋白在微生物适应锌匮乏环境、维持酶活性(如锌超氧化物歧化酶)中的调控机制。 ▶锌转运蛋白突变体/变体功能筛选:对锌转运蛋白的不同突变体、等位变体进行功能验证,评估氨基酸位点突变对转运活性的影响,助力蛋白结构 - 功能关系研究。 上一篇酵母铵转运缺陷株互补验证下一篇酵母锰转运缺陷株互补验证 |
