PF00009 | Elongation factor Tu GTP binding domain (GTP_EFTU) | Elongation factor Tu GTP binding domain | This domain contains a P-loop motif, also found in several other families such as Pfam:PF00071, Pfam:PF00025 and Pfam:PF00063. Elongation factor Tu consists of three structural domains, this plus two C-terminal beta barrel domains. | Domain | |
PF11987 | Translation-initiation factor 2 (IF-2) | Translation-initiation factor 2 | IF-2 is a translation initiator in each of the three main phylogenetic domains (Eukaryotes [1], Bacteria [2] and Archaea [3]). IF2 interacts with formylmethionine-tRNA, GTP, IF1, IF3 and both ribosomal subunits [2]. Through these interactions, IF2 pr ... | Domain |
