Chains	Accession	Name	Description	Comments	Source
A	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
A	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
B	PF07541	Eukaryotic translation initiation factor 2 alpha subunit (EIF_2_alpha)	Eukaryotic translation initiation factor 2 alpha subunit	-	Family
B	PF00575	S1 RNA binding domain (S1)	S1 RNA binding domain	The 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
C	PF01873	Domain found in IF2B/IF5 (eIF-5_eIF-2B)	Domain found in IF2B/IF5	-	Family
