Specifications
SUMOstar Fusion Protein TechnologyThe pY-secSUMOstar vector enables expression and secretion of SUMOstar fusions in Pichia pastoris. Protein expression is driven by the primary alcohol oxidase (AOX1) promoter, which is both tightly regulated and highly inducible. The alpha mating factor (S. cerevisiae) targets the fusion protein to the secretory pathway, while both a FLAG and a His6 tag preceed SUMOstar for convenient purification. Chromosomal integration is accomplished by DNA linearization within the promoter using a variety of convenient endonuclease restriction sites, while mult-copy integrants can be obtained through strain selection against increasing concentrations of the antibiotic Zeocin.This product is protected by one or more US or Foreign patents. By purchasing this product, the purchaser agrees to comply with the terms of our Limited Use Label License.

Life Sensors的泛素和泛素链泛素是一种小的多肽，通过其C端与目标蛋白上的赖氨酸的ε-氨基缀合。这种缀合称为单泛素化。随后，可以利用遍在蛋白表面上的七个赖氨酸残基（K6，K11，K27，K29，K33，K48，K63）中的任何一个，将额外的遍在蛋白部分与初始遍在蛋白结合。这种泛素链形成称为多泛素化。泛素的酶结合是通过一系列酶进行的，即泛素激活酶E1，泛素结合酶E2和泛素连接酶E3。蛋白质的泛素化在细胞中是可逆的。单泛素化和多泛素化的链均被去泛素化酶催化的水解作用裂解 （DUB）。LifeSensors在遍在泛素途径的所有水平的酶（包括E1，E2和E3酶和DUB）上都有丰富的经验。LifeSensors对蛋白质纯化的广泛了解使我们能够生产大约30种E2酶，20种E3酶和35个DUB，并具有定制表达的能力。此外，我们广泛的检测方法简化了确认酶活性和确定E2-E3对兼容性的过程，并确保您可以选择最能解决希望探索的特定，关键生物学问题的酶。LifeSensors已为您的研究开发了多种泛素衍生物，包括用于结合相互作用研究的DUB耐药性聚泛素链，用于DUB分析和筛选的泛素结合物（荧光团和报告酶），选择性泛素链（二，三和四环素）泛素链）用于DUB特异性和结合测定，位点特异性赖氨酸泛素突变体用于E3连接酶和DUB选择性测定。
