Fig. 6: The scheme of GTPBP1-catalyzed mRNA decoding.
From: Structural mechanism of mRNA decoding by mammalian GTPase GTPBP1

GTPBP1 achieves higher accuracy than eEF1A-catalyzed decoding due to distinct protein architectures and interactions with the ribosome (small subunit cyan; large subunit yellow) and aa-tRNA (green) during initial selection and proofreading.
