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
PF07541Eukaryotic translation initiation factor 2 alpha subunit (EIF_2_alpha)Eukaryotic translation initiation factor 2 alpha subunit- Family
PF00575S1 RNA binding domain (S1)S1 RNA binding domainThe S1 domain occurs in a wide range of RNA associated proteins. It is structurally similar to cold shock protein which binds nucleic acids. The S1 domain has an OB-fold structure.Domain
PF01873Domain found in IF2B/IF5 (eIF-5_eIF-2B)Domain found in IF2B/IF5- Family
