Project description:Hydrogenases are a critical component of H2-dependent energy-conservation pathways in Methanosarcina barkeri. To allow phenotypic analysis of the hydrogenases, we constructed mutants lacking the frhADGB, freAEGB, vhtGACD, vhxGAC and echABCDEF operons, individually and in all possible combinations. In addition to measuring the effect of each deletion on growth, methane production, and hydrogenase activity, the effect on gene expression was measured by RNA sequencing to detect potential transcriptional regulation by the hydrogenases.
