Abstract
- Overlapping genes share the same DNA segment, but encode different proteins. Only few overlapping genes in bacteria have been described so far. In this work overlapping genes in pathogenic Escherichia coli were experimentally investigated. Overlapping open reading frames were translationally arrested. Some of these mutants showed a phenotype which is clear evidence for functional overlapping genes. Additionally, the genome of strain E.coli O157:H7 EDL933 used in this work was re-sequenced.<br />Überlappende Gene teilen sich das gleiche DNS-Segment, codieren aber für unterschiedliche Proteine. Bisher sind nur wenige überlappende Gene in Bakterien bekannt. In dieser Arbeit wurden überlappende Gene in pathogenem Escherichia coli experimentell untersucht. Dazu wurden überlappende offene Leserahmen translational arretiert. Einige Mutanten zeigten einen Phänotyp, was ein klarer Hinweis auf funktionale überlappende Gene ist. Zusätzlich wurde das Genom des für diese Arbeit verwendeten Stammes E.coli O157:H7 EDL933 re-sequenziert.
