The primary structure of two proteins from the small ribosomal subunit of rice.

We isolated two rice cDNAs which encode an open reading frame of 117 amino acids or 82 amino acids. Their deduced amino acid sequence correspond to the ribosomal proteins (r-protein). A comparison of the amino acid sequence shows that the deduced amino acid sequence of one cDNA is homologous to the rat r-protein S20 and Xenopus r-protein S22. Another encoded products with a high degree of homology to the rat r-protein S21 and the yeast r-protein YS25.
