PF00009Elongation factor Tu GTP binding domain (GTP_EFTU)Elongation factor Tu GTP binding domainThis 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
PF09173Initiation factor eIF2 gamma, C terminal (eIF2_C)Initiation factor eIF2 gamma, C terminalMembers 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
