Protein methylation is an important modulator of signal transduction pathways, but methyltransferases themselves may also be modulated. Hu et al. (2017) demonstrate in this issue of Molecular Cell that S-nitrosylation selectively modulates enzymatic activity of a protein arginine methyltransferase vital to abiotic stress tolerance.

调节调节剂：一氧化氮对蛋白质甲基化的调节

蛋白质甲基化是信号转导途径的重要调节剂，但是甲基转移酶本身也可以被调节。Hu等。（2017）证明的此问题分子细胞即小号-nitrosylation选择性调节甲基转移对非生物胁迫耐受性的重要的蛋白质精氨酸酶活性。
