title: Conserved amino acid residues in the primary structure of ribosomal protein S20 from selected gram-negative bacteria.
abstract: Partial DNA sequences encoding ribosomal protein S20 have been determined for a number of Gram-negative bacteria including three species of Aeromonas, Klebsiella pneumoniae, Proteus mirabilis, and Salmonella typhimurium and compared to the known sequence from Escherichia coli. The derived amino acid sequence is well conserved, particularly in the C-terminal one-third of S20. In contrast, there is much less conservation of the nucleotide sequence or potential secondary structure in the corresponding mRNA.
