Ribosome-dependent ATPase that functions in cytoplasmic translation elongation (By similarity). 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. Belongs to the ABC transporter superfamily. ABCF family. EF3 subfamily.
