Elongation factor G, mitochondrial (Gfm1)

Mitochondrial GTPase that catalyzes the GTP-dependent ribosomal translocation step during translation elongation. In this step, the ribosome changes from the pre-translocational (PRE) to the post-translocational (POST) state as the newly formed A- site-bound peptidyl-tRNA and P-site-bound deacylated tRNA proceed to the P and E sites, respectively.

Catalyzes the coordinated movement of the two tRNA molecules, the mRNA and conformational changes in the ribosome. Doesn't mediate the disassembly of ribosomes from messenger RNA in the termination of mitochondrial protein biosynthesis.
