Cloning and nucleotide sequencing of the genes rimI and rimJ which encode enzymes acetylating ribosomal proteins S18 and S5 of Escherichia coli K12.
Yoshikawa A., Isono S., Sheback A., Isono K.
The rimI gene of Escherichia coli K12, which encodes an enzyme catalysing acetylation of the N-terminal alanine of ribosomal protein S18, has been cloned into a mini-F plasmid pRE432 and characterized at the molecular level. Similarly, the rimJ gene, which encodes another acetylating enzyme that i ... >> More
The rimI gene of Escherichia coli K12, which encodes an enzyme catalysing acetylation of the N-terminal alanine of ribosomal protein S18, has been cloned into a mini-F plasmid pRE432 and characterized at the molecular level. Similarly, the rimJ gene, which encodes another acetylating enzyme that is specific for ribosomal protein S5, has been cloned and characterized. From the nucleotide sequence data for the two genes the RimI enzyme was deduced to contain 161 amino acid residues with a calculated molecular weight (Mr) of 18232 and the RimJ enzyme contains 194 amino acid residues with a calculated Mr of 22687. The proteins produced from the two genes in maxi-cells were identified by electrophoresis on acrylamide gels and their operon structure was analysed by insertional mutagenesis with transposon gamma delta (Tn1000) and by measuring the size of their transcripts. Their structural homology was analysed by DNA hybridization and by calculation with computer programs. There is only a low level of overall homology between the two genes except for a 3' terminal region in which a significant degree of homology was noticed. << Less

Posttranslational Modifications of Ribosomal Proteins in Escherichia coli.
Nesterchuk M.V., Sergiev P.V., Dontsova O.A.
А number of ribosomal proteins inEscherichia coliundergo posttranslational modifications. Six ribosomal proteins are methylated (S11, L3, L11, L7/L12, L16, and L33), three proteins are acetylated (S5, S18, and L7), and protein S12 is methylthiolated. Extra amino acid residues are added to protein ... >> More
А number of ribosomal proteins inEscherichia coliundergo posttranslational modifications. Six ribosomal proteins are methylated (S11, L3, L11, L7/L12, L16, and L33), three proteins are acetylated (S5, S18, and L7), and protein S12 is methylthiolated. Extra amino acid residues are added to protein S6. С-terminal amino acid residues are partially removed from protein L31. The functional significance of these modifications has remained unclear. These modifications are not vital to the cells, and it is likely that they have regulatory functions. This paper reviews all the known posttranslational modifications of ribosomal proteins inEscherichia coli. Certain enzymes responsible for the modifications and mechanisms of enzymatic reactions are also discussed. << Less
