RESUMO
The gene encoding the selenoprotein A component of glycine reductase was isolated from Clostridium purinolyticum. The nucleotide sequence of this gene (grdA) was determined. The opal termination codon (TGA) was found in-frame at the position corresponding to the location of the selenocysteine residue in the gene product. A comparison of the nucleotide sequences and secondary mRNA structures corresponding to the selenoprotein A gene and the fdhF gene of Escherichia coli formate dehydrogenase shows that there is a similar potential for regulation of the specific insertion of selenocysteine at the UGA codon.
