Abstract:
The amino acid (aa) sequence of rat ribosomal (r) protein L9 was deduced from the nucleotide (nt) sequence in a recombinant cDNA and confirmed from the N-terminal aa sequence of the protein. L9 contains 192 aa and has an Mr of 21879. Hybridization of the cDNA to digests of nuclear DNA suggests that there are 20-23 copies of the L9 gene. The mRNA for the protein is about 800 nt in length. Rat L9 is related to Saccharomyces cerevisiae YL11, Methanococcus vannielii L6, Escherichia coli L6 and other members of the prokaryotic L6 family. The protein contains a possible internal duplication of 11 aa.
