Ribosome-dependent ATPase that promotes the translation of proteins required for detoxification of reactive oxygen species (PubMed:33260587). Required for the ATP-dependent release of deacylated tRNA from the ribosomal E-site during protein biosynthesis (By similarity). Stimulates the eEF1A-dependent binding of aminoacyl-tRNA to the ribosomal A-site, which has reduced affinity for tRNA as long as the E-site is occupied (By similarity). ATP + H2O = ADP + H(+) + phosphate Protein biosynthesis; polypeptide chain elongation. Monomer. Expressed in vegetatively growing cells at very low levels. Increases in mild (0.5 mM) hydrogen peroxide stress, and decreases in stronger (1 mM) hydrogen peroxide stress. Decreases translation of proteins required for detoxification of reactive oxygen species (PubMed:33260587). Sensitive to hydrogen peroxide (PubMed:33260587). Increases GRX1 mRNA level during vegetative growth (PubMed:33260587). Normal vegetative cell population growth on glucose, galactose, and glycerol carbon sources, at high temperature, and at standard temperature (PubMed:9778796, PubMed:33260587). Normal mating and sporulation (PubMed:9778796). Present with 125 molecules/cell in log phase SD medium. Belongs to the ABC transporter superfamily. ABCF family. EF3 subfamily.
