EF-Tu/IF-2/RF-3 family GTPase
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. [1]. 7491491.

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]. [1]. 7491491.
