Nucleotide sequence of the genes for ribosomal proteins HS15 and HSH from Haloarcula marismortui: an archaeon-specific gene cluster.
The nucleotide sequences of the genes for two ribosomal proteins, HS15 and HSH, from the archaeon Haloarcula marismortui, have been determined. The genes were found in a cluster together with another open reading frame with a probable regulatory function. HS15 and HSH have counterparts in eucarya. HS15 is significantly homologous to S19 from frog (Xenopus laevis). HSH is related to S37 from yeast (Saccharomyces cerevisiae) and S27 from fly (Drosophila melanogaster), as well as to other members of the S27 family. Eubacterial counterparts were not found, suggesting that these proteins are 'extra proteins' that are absent in eubacterial ribosomes.
