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.

PF09173Initiation factor eIF2 gamma, C terminal (eIF2_C)Initiation factor eIF2 gamma, C terminalMembers of this family, which are found in the initiation factors eIF2 and EF-Tu, adopt a structure consisting of a beta barrel with Greek key topology. They are required for formation of the ternary complex with GTP and initiator tRNA [1].Domain
