RatA is not a toxin but serves as a ubiquinone shuttle

2026-05-05

Abstract excerpt

Conflicting roles have been proposed for the E. coli protein RatA. Initially described as a ribosome targeting toxin, a later report pronounced it the bacterial homologue to the inner mitochondrial membrane protein Coq10. Coq10 proteins are conserved from prokaryotes to human and implicated to serve a lipid chaperone role in the biosynthesis of ubiquinone, a crucial electron carrier during aerobic respiration. We...
