| E [auth O], M [auth P] | 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 |
| E [auth O], M [auth P] | PF09173 | Initiation factor eIF2 gamma, C terminal (eIF2_C) | Initiation factor eIF2 gamma, C terminal | Members of this family, which are found in the initiation factors eIF2 and EF-Tu, adopt a structure consisting of a beta barrel with Greek key topology. They are required for formation of the ternary complex with GTP and initiator tRNA [1]. | Domain |
| E [auth O], M [auth P] | PF03144 | Elongation factor Tu domain 2 (GTP_EFTU_D2) | Elongation factor Tu domain 2 | Elongation factor Tu consists of three structural domains, this is the second domain. This domain adopts a beta barrel structure. This the second domain is involved in binding to charged tRNA [1]. This domain is also found in other proteins such as e ... | Domain |
