pubmed:abstractText |
Escherichia coli strain 15-28 is a mutant with a defect in ribosome synthesis that caused the accumulation of ribonucleoprotein ('47S') particles during exponential growth. These particles are precursors to 50S ribosomes that lack three ribosomal proteins. Peptidyltransferase activity and binding at the peptidyl site of the peptidyltransferase centre are greatly decreased in 47S particles. Both these activities are lower in the 50S and 70S ribosomes of strain 15-28 than in its parent. Unusual assembly of the larger ribosomal subunit in strain 15-28 may produce completed ribosomes with diminished biological activity.
