Comparison of the primary structure of SseEF1As and various others eEF1A proteins (see Table 3). The alignment was performed using MegAlign software. Dots represent identity with SseEF1A1, and dashes represent gaps. G1 to G4 indicate the critical regions involved in GDP/GTP exchange and GTP hydrolysis. The consensus sequence composed of the three consensus elements GXXXXGK (G14-K20), DXXG (D91-G94), and NKXD (N153-D156) present in the GTP-binding domain is shaded in grey. The GTP-binding elongation factor signature corresponding to amino acids 61 to 76 is boxed.
