Title: Nucleotide sequence of the rodA gene, responsible for the rod shape of Escherichia coli: rodA and the pbpA gene, encoding penicillin-binding protein 2, constitute the rodA operon. | Journal: Journal of bacteriology. 1989 Jan;171(1):558-60 | Authors: Matsuzawa H, Asoh S, Kunai K, Muraiso K, Takasuga A, Ohta T. | Abstract: The rodA gene, which is responsible for the rod shape of Escherichia coli, was located 5 nucleotides downstream of another rod-shape-determining gene, pbpA, encoding penicillin-binding protein 2. The coding region for the RodA protein was 1,110 base pairs in length. Two plasmids, carrying a rodA-lacZ gene fusion with and without the pbpA promoter upstream of the gene fusion, were constructed. On the basis of the difference between the expression levels of the beta-galactosidase activity dependent on and independent of the pbpA promoter, we concluded that the pbpA and rodA genes constitute a single transcriptional unit called the rodA operon. | See full PubMed entry: http://www.ncbi.nlm.nih.gov/pubmed/2644207 |
