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.

protein-synthesizing GTPase (elongation factor Tu)  M-CSA #535

Elongation factor Tu hydrolyses GTP to give GDP and Pi, thus providing the free energy that the ribosome needs to incorporate amino acids into the growing polypeptide. As such, it shows homology to other GTP binding proteins such as the oncogene ras, but may show a different mechanism of GTP hydrolysis. Many antibiotics are able to inhibit EFTu, making study of its mechanism particularly useful in view of the possibility of synthesising new antibiotics.
