A, B	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

This entry represents the C-terminal RIFT beta barrel domain found in the Selenocysteine-specific elongation factor eEFSec [1]. Selenocysteine is the only proteinogenic amino acid encoded by a recoded in-frame UGA codon that does not operate as the canonical opal stop codon. A specialised translation elongation factor, eEFSec in eukaryotes and SelB in prokaryotes, promotes selenocysteine incorporation into selenoproteins [1].	Domain
A, B	PF21208	Selenocysteine-specific elongation factor, eukaryotes, 3rd domain (euk_SelB_III)	Selenocysteine-specific elongation factor, eukaryotes, 3rd domain	This domain is found in Selenocysteine-specific elongation factor from humans (SelB) and similar sequences from eukaryotes. SelB is a translation factor necessary for the incorporation of selenocysteine into proteins. This protein adopts a chalice-li ...	This domain is found in Selenocysteine-specific elongation factor from humans (SelB) and similar sequences from eukaryotes. SelB is a translation factor necessary for the incorporation of selenocysteine into proteins. This protein adopts a chalice-like structure composed of four domains. This entry represents the third domain, which shows seven antiparallel beta-strands and a long alpha-helix [1].	Domain
A, B	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 ...	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 elongation factor G and translation initiation factor IF-2. This domain is structurally related to Pfam:PF03143, and in fact has weak sequence matches to this domain.	Domain
