Hydrophobicity and pI of ribosomal proteins in the large subunit of the ribosome from nine organisms.
Red solid squares, 50 S ribosomal proteins from halophilic archaea H. marismortui, H. jeotgali, and halophilic archaeon DL31; blue solid circles, eukaryotic 60 S ribosomal proteins from S. cerevisiae and T. thermophila; black open circles, bacterial 50 S ribosomal proteins from E. coli, T. thermophilus, and D. radiodurans; orange crosses, 50 S ribosomal proteins from non-halophilic archaea S. solfataricus and M. thermautotrophicus. The vertical dotted line denotes the physiological pH of 7.4.
