>gnl|CDD|58087 cd03696, selB_II, selB_II: this subfamily represents the domain of elongation factor SelB, homologous to domain II of EF-Tu. SelB may function by replacing EF-Tu. In prokaryotes, the incorporation of selenocysteine as the 21st amino acid, encoded by TGA, requires several elements: SelC is the tRNA itself, SelD acts as a donor of reduced selenium, SelA modifies a serine residue on SelC into selenocysteine, and SelB is a selenocysteine-specific translation elongation factor. 3' or 5' non-coding elements of mRNA have been found as probable structures for directing selenocysteine incorporation..
