一般描述
OverExpress™ 电感受态和化学感受态细胞是可以有效表达所有种类生物体（包括真细菌、酵母、植物、病毒和哺乳动物）的有毒蛋白质的大肠杆菌。这些新菌株表达有毒蛋白质的有效性已在350多篇论文中得到验证。OverExpress™菌株含有从表型上选择的基因突变，以产生对有毒蛋白质的耐受性。C41(DE3) 菌株来源于 BL21(DE3)。该菌株至少有一处突变，其防止了与许多重组有毒蛋白表达相关的细胞死亡。菌株C43（DE3）来源于C41（DE3），是通过选择对不同毒性蛋白的抗性而得到的，并且可以表达一组不同的C41（DE3）的毒性蛋白。OverExpress C41（DE3）pLysS和C43（DE3）pLysS还带有抗氯霉素的质粒，该质粒可编码T7溶菌酶，其是T7 RNA聚合酶的一种天然抑制剂。含有pLysS的细胞会产生少量的T7溶菌酶。这些菌株用于抑制诱导以前T7 RNA聚合酶的基础表达，从而使编码特别有毒的蛋白质的重组体保持稳定。

Protein arginine methyltransferases (PRMTs) catalyze the posttranslational methylation of arginine using S-adenosylmethionine (SAM) as a methyl-donor. The PRMT family is widely expressed and has been implicated in biological functions such as RNA splicing, transcriptional control, signal transduction, and DNA repair.

Protein arginine methyltransferase (PRMT) 8 is unique among the PRMTs, as it has a highly restricted tissue expression pattern and an N terminus that contains two automethylation sites and a myristoylation site. PRMTs catalyze the transfer of a methyl group
