Identifiering av promotorregionen för Cyt c Id1 samt undersökning av genuttrycket i närvarooch frånvaro av syre / Identification of the promoter region for Cyt c Id-1 and investigation of geneexpression in the presence and absence of oxygen

Nabo, Slava January 2023 (has links)
In this work, the identification of the promoter for c-cytochromes Cyt c Id-1 in Ideonella dechloratans has been investigated. Additionally, the study examined investigating whether gene expression is affected by the presence and absence of oxygen. This was investigated by amplifying the promoter region of Cyt c Id-1 (389 bp) and then cloning it into a reporter vector lacking a functional promoter for the upstream gene β-galactosidase. The reporter vector was transformed into E. coli RM101 and grown under both aerobic and anaerobic conditions. To examine the gene expression of Cyt c Id-1 the activity of β-galactosidase has been measured in both the aerobic and anaerobic cultures. The result showed that the gene is induced more in an anaerobic environment than in an aerobic environment, by comparing the activity of β-galactosidase under aerobic and anaerobic conditions. / I detta arbete har identifiering av promotorn för c-cytokromer Cyt c Id-1 i Ideonella dechloratans undersökts, samt att undersöka om genuttrycket påverkas av närvaro och frånvaro av syre. Detta är undersökts genom att amplifiera promotorregionen för Cyt c Id-1 (389 bp) för att sedan klona in den in i en reportervektor som saknar en fungerande promotor för uppströms genen β-galaktosidas. Reportervektorn transformerades till E. coli RM101 och odlades under både aeroba och anaeroba förhållanden.  För att undersöka genuttrycket av Cyt c Id-1 har aktiviteten hos β-galaktosidas uppmätts i både de aeroba och anaeroba odlingarna. Resultatet visat att genen induceras mer i anaerob miljö än i aerob miljö, genom att jämföra aktiviteten av β-galaktosidas under både aerob och anaerob förhållande.
