The nucleotide sequence has been determined of a 4700 by region from a ribosomal protein gene cluster of Halobacterium marismortui (Haloarcula marismortui), which is equivalent to part of the spectinomycin operon of Escherichia coli. The genes were localized on the recombinant λEMBL3 clone PP*7, which also contains several other ribosomal protein genes from the DNA region in H. marismortui equivalent to the linked S10/spc operon. The genes analysed encode ten ribosomal proteins, namely HmaL5, HmaS14, HmaS8, HmaL6, HL5, HL24, HmaL18, HmaS5, HmaL30 and HmaL15. The gene organization of the archaebacterial cluster is similar to that in eubacteria but has two additional genes, namely those encoding HL5 and HL24, which were identified as extra proteins that are apparently not present in E. coli. These correspond to the gene products of orfd and orfe in Methanococcus vannielii and also have eukaryotic counterparts.
