Nucleotide sequences of cloned cDNA fragments specific for six Xenopus laevis ribosomal proteins.
We have previously constructed and selected six recombinant plasmids containing cDNA sequences specific for different ribosomal proteins of Xenopus laevis (Bozzoni et al., 1981). DNA cloned in these plasmids have been isolated and sequenced. Amino acid sequences of the corresponding portions of the proteins have been derived from DNA sequences; they are arginine- and lysine-rich as expected for ribosomal proteins. One of the cDNA sequences has an open reading frame also on the strand complementary to the one coding for the ribosomal protein; this fragment has inverted repeats twenty nucleotides lone at the two ends. The codon usage for the six sequences appears to be non-random with some differences among the ribosomal proteins analysed.
