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
A	PF03764	Elongation factor G, domain IV (EFG_IV)	Elongation factor G, domain IV	This domain is found in elongation factor G, elongation factor 2 and some tetracycline resistance proteins and adopts a ribosomal protein S5 domain 2-like fold.	Domain
