Nucleotide sequence of a gene cluster encoding NusG and the L11-L1-L10-L12 ribosomal proteins from the thermophilic archaeon Sulfolobus solfataricus.

The complete nucleotide sequence of a gene cluster encoding the NusG and the L 11-L1-L10-L12 ribosomal proteins from the thermophilic crenarchaeon Sulfolobus solfataricus has been determined. The genes are arranged in the same order as the equivalent genes in the rif region of Escherichia coli. The ribosomal proteins exhibit between 66% (L10) and 80% (L12) identity with their respective equivalents from Sulfolobus acidocaldarius. The short distance (5 nucleotides) between the nusG stop codon and the L11 start codon suggests that nusG and the genes for the ribosomal proteins are transcribed as a single unit.
