Specific DNA binding of a potential transcriptional regulator, inosine 5'-monophosphate dehydrogenase-related protein VII, to the promoter region of a methyl coenzyme m reductase I-encoding operon retrieved from Methanothermobacter thermautotrophicus strain DeltaH.


Two methyl coenzyme M reductases (MCRs) encoded by the mcr and mrt operons of the hydrogenotrophic methanogen Methanothermobacter thermautotrophicus DeltaH are expressed in response to H(2) availability. In the present study, cis elements and trans-acting factors responsible for the gene expression of MCRs were investigated by using electrophoretic mobility… (More)
