Die dissimilatorische APS-Reduktase -Vorkommen, Phylogenie, Struktur und Anwendung in der funktionellen Genanalyse

Within this doctoral thesis, the distribution, phylogeny and structure of the dissimilatory APS reductase (AprBA) of sulfate-reducing and sulfur-oxidizing prokaryotes (SRP and SOP) has been analyzed. An assay for aprA-based functional gene analysis was developed for determination of the SRP and SOP diversity in environmental samples. In addition, the distribution of the sulfate thiol hydrolase (SoxB, a component of the thiosulfate-oxidizing multi-enzyme system Sox) in SOP was investigated.
