The nucleotide sequence of the ribosomal protein gene rpsO (S15) and its flanking region were determined. The amino acid sequence of S15 protein deduced from the nucleotide sequence is in good agreement with the published amino acid sequence with one exception. The nucleotide sequence shows two prob

โฆ Synopsis
We determined the nucleotide sequence of a DNA fragment containing the ftsI gene coding for the penicillin-binding protein 3 (PBP-3), an indispensable enzyme for cell division of Escherichia coli. The entire ftsI gene was within the 2.8 kilobase PvuII fragment derived from the chromosomal segment on pLC26-6 (Nishimura et al. 1977). The coding region for PBP-3 was identified by comparison with the N-terminal amino acid sequence of in vitro synthesized PBP-3. The structural gene for ftsI consisted of 1,764 base-pairs coding for a 588 amino acid residue-polypeptide with a molecular weight of 63,850. PBP-3 synthesized in vitro showed a lower mobility in SDS-gel electrophoresis than that of the authentic PBP-3, suggesting that the primary translation product of the ftsI gene may be processed to yield mature PBP-3.

The genes for the ribosomal proteins $9 (rpsI) and L13 (rplM) of Escherichia coli have been cloned into a 2 phage vector termed L47.1. The two genes were identified by infecting UV-light irradiated cells with the resultant phages and analyzing the protein products by two-dimensional gel electrophore
The DNA of the promoter region of omp T, including the putative start for the pro-Omp T protein (pro-protein a), has been sequenced. Previous studies showed that trypsin inhibitors prevent the processing of pro-Omp T to Omp T protein which led to the prediction that the processing site would be a ly
