Elongation factor SelB uses several methods to recognize the selenocysteine insertion sequence found in messenger RNA. The insertion sequence forms a hairpin loop with an unstacked guanine base in the loop. This guanine forms The planar base is also sandwiched between in the protein, which form a tight hydrophobic pocket.
