General description
Rosetta宿主菌株是BL21衍生物，旨在增强真核蛋白的表达，该蛋白含有在大肠杆菌中很少使用的密码子。这些菌株在兼容的氯霉素抗性质粒上为AGG、AGA、AUA、CUA、CCC、GGA密码子提供tRNA。因此，Rosetta菌株提供了“通用”翻译，否则该翻译受大肠杆菌密码子使用的限制。tRNA基因由其天然启动子驱动。在Rosetta（DE3）pLysS中，稀有tRNA基因存在于携带T7溶菌酶基因的相同质粒上。
DE3表明宿主是λDE3的溶原菌，因此在lacUV5启动子的控制下携带T7 RNA聚合酶基因的染色体拷贝。这样的菌株适用于通过用IPTG诱导从克隆在pET载体中的靶基因生产蛋白质。

Covalent kinase inhibitors, which typically target cysteine residues, represent an important class of clinically relevant compounds. Approximately 215 kinases are known to have potentially targetable cysteines distributed across 18 spatially distinct locations proximal to the ATP-binding pocket. However, only 40

The functions of nervous and neuroendocrine systems rely on fast and tightly regulated release of neurotransmitters stored in secretory vesicles through SNARE-mediated exocytosis. Few proteins, including tomosyn (STXBP5) and amisyn (STXBP6), were proposed to negatively regulate exocytosis. Little is known
