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

This domain is found in Elongation factor SelB from Aquifex aeolicus and similar bacterial proteins. SelB is a selenocysteine(Sec)-specific elongation factor that brings the selenocysteinyl-tRNA(Sec) to the ribosome. It consists of three EF-Tu-like domains (D1-3, where Pfam:PF00009 is the first one), followed by four winged-helix domains (WHD1-4). This entry represents the first winged-helix domain (WHD1) [1].

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
