In this issue ofCell Chemical Biology,Pandey et al. (2018)identified that mitochondrial cysteine desulfurase provides the sulfur species used for tRNALys, tRNAGlu, and tRNAGlnthiouridine modification in the cytoplasm. A low-mass sulfur species is exported by the mitochondrial Atm1 transporter and utilized in the thio-modifications.

内部产生的硫：胞质tRNA硫尿素化

在本期《细胞化学生物学》中，Pandey等人。（2018）确认线粒体半胱氨酸脱硫酶提供了用于细胞质中tRNALys，tRNAGlu和tRNAGln硫尿苷修饰的硫物种。线粒体Atm1转运蛋白输出低质量的硫，并用于硫修饰。
