The microbial metabolite preQ1 modifies tRNA, reduces cell proliferation, and decreases protein translation. This is mediated by IRE1-dependent cleavage of preQ1-modified tRNAs.

Two microbiome metabolites compete for tRNA modification to impact mammalian cell proliferation and translation quality control
