Engemann S, Herfurth E, Briesemeister U, Wittmann-Liebold B. Amino acid sequence of the ribosomal protein HS23 from the halophilic Haloarcula marismortui and homology studies to other ribosomal proteins. J Protein Chem. 1995;14(4):189-95.
The ribosomal protein HS23 from the 30S subunit of the extreme halophilic Haloarcula marismortui, belonging to the group of archaea, was isolated either by RP-HLPLC or two-dimensional polyacrylamide gel electrophoresis. The complete amino acid sequence was determined by automated N-terminal microsequencing. The protein consists of 123 residues with a corresponding molecular mass of 12,552 Da as determined by electrospray mass spectroscopy; the pI is 11.04. Homology studies reveal similarities to the eukaryotic ribosomal protein S8 from Homo sapiens, Rattus norvegicus, Leishmania major, and Saccharomyces cerevisiae.
