A, C, E, G	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, C, E, G	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.

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

The crystal structure of human eRF1 is known [1]. The o ...	The release factor eRF1 terminates protein biosynthesis by recognising stop codons at the A site of the ribosome and stimulating peptidyl-tRNA bond hydrolysis at the peptidyl transferase centre. The crystal structure of human eRF1 is known [1]. The overall shape and dimensions of eRF1 resemble a tRNA molecule with domains 1, 2, and 3 of eRF1 corresponding to the anticodon loop, aminoacyl acceptor stem, and T stem of a tRNA molecule, respectively. The position of the essential GGQ motif at an exposed tip of domain 2 suggests that the Gln residue coordinates a water molecule to mediate the hydrolytic activity at the peptidyl transferase centre. A conserved groove on domain 1, 80 A from the GGQ motif, is proposed to form the codon recognition site [1]. This family also includes other proteins for which the precise molecular function is unknown. Many of them are from Archaebacteria. These proteins may also be involved in translation termination but this awaits experimental verification.	Domain
