摘要: By cross-hybridization with a cDNA probe for the Xenopus laevis ribosomal protein L1 we have been able to isolate homologous genes from Saccharomyces cerevisiae genomic library. We shown that these code which was previously named L2. In yeast, like in X. laevis, are present two copies per haploid genome and, unlike vertebrate counterpart, they do not contain introns. Amino acid comparison of and S. L2 proteins has presence highly conserved domain embedded very divergent sequences. Although sequences poorly homologous, confer an overall secondary structure folding species.
