| multiple controls regulate the expression of mobe, an hnh homing endonuclease gene embedded within a ribonucleotide reductase gene of phage aeh1. | mobile genetic elements have the potential to influence the expression of genes surrounding their insertion site upon invasion of a genome. here, we examine the transcriptional organization of a ribonucleotide reductase operon (nrd) that has been invaded by an hnh family homing endonuclease, mobe. in aeromonas hydrophila phage aeh1, mobe has inserted into the large-subunit gene (nrda) of aerobic ribonucleotide reductase (rnr), splitting it into two smaller genes, nrda-a and nrda-b. this gene org ... | 2007 | 17449612 |
