A [auth C]	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 [auth C]	PF03143	Elongation factor Tu C-terminal domain (GTP_EFTU_D3)	Elongation factor Tu C-terminal domain	Elongation factor Tu consists of three structural domains, this is the third domain. This domain adopts a beta barrel structure. This the third domain is involved in binding to both charged tRNA [1] and binding to EF-Ts Pfam:PF00889 [2].	Domain

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
D	PF04564	U-box domain (U-box)	U-box domain	The U-box is a domain of ~70 amino acids that is present in proteins from yeast to human. It consists of the beta-beta-alpha-beta-alpha- fold typical of U-box and RING domains. The central alpha helix is flanked by two prominent surface-exposed loop ...	The U-box is a domain of ~70 amino acids that is present in proteins from yeast to human. It consists of the beta-beta-alpha-beta-alpha- fold typical of U-box and RING domains. The central alpha helix is flanked by two prominent surface-exposed loop regions. This domain is one class of E3 ligases, involved in the ubiquitination process [1-3]. This domain is related to the Ring finger Pfam:PF00097 but lacks the zinc binding residues [4].	Domain
