>gnl|CDD|133287 cd01887, IF2_eIF5B, IF2/eIF5B (initiation factors 2/ eukaryotic initiation factor 5B) subfamily. IF2/eIF5B contribute to ribosomal subunit joining and function as GTPases that are maximally activated by the presence of both ribosomal subunits. As seen in other GTPases, IF2/IF5B undergoes conformational changes between its GTP- and GDP-bound states. Eukaryotic IF2/eIF5Bs possess three characteristic segments, including a divergent N-terminal region followed by conserved central and C-terminal segments. This core region is conserved among all known eukaryotic and archaeal IF2/eIF5Bs and eubacterial IF2s. Length = 168
