Artificial aquaporins are synthetic molecules that mimic the structure and function of natural aquaporins (AQPs) in cell membranes. The development of artificial aquaporins would provide an alternative strategy for treatment of AQP-related diseases. In this report, an artificial aquaporin has been constructed from amino-terminated tubular molecule, which operates in a unimolecular mechanism. The artificial
catalyzing methylation reactions from carbon-atoms to nucleophilic atoms making it a unique and versatile alkylating agent. TsrM is able to directly transfer methyl groups on the less reactive carbon atom of the indole ring and to install several methyl groups on its substrate. TsrM has thus unique properties among radical SAM enzymes by notably catalyzing non-radical reactions. (SAM: S-adenosyl-L-methionine)
TsrM 是一种 B 12依赖性自由基 SAM 酶,可催化从碳原子到亲核原子的甲基化反应,使其成为一种独特且用途广泛的烷化剂。TsrM 能够直接转移吲哚环反应性较低的碳原子上的甲基,并在其底物上安装几个甲基。因此,通过显着催化非自由基反应,TsrM 在自由基 SAM 酶中具有独特的特性。(SAM:S-腺苷-L-蛋氨酸)。
