Abstract

Eukaryotic queuosine tRNA modification depends on the intake of microbial queuine. In a recent issue of Nature Cell Biology, Zhang et al. show that pre-queuosine 1 (preQ<sub>1</sub>), an intermediate of the bacterial queuine biosynthesis pathway, competes with queuine for the same mammalian tRNA targets to antagonistically modulate protein translation and cell proliferation.
