The dual role of a multi-heme cytochrome in methanogenesis: MmcA is important for energy conservation and carbon metabolism in Methanosarcina acetivorans
D. D. Nayak, D. Gupta, B. Downing
This study investigates the roles of the Rnf complex and MmcA in Methanosarcina acetivorans, showing MmcA is essential for acetoclastic methanogenesis but not for growth on methylated compounds, and reveals alternative ferredoxin regeneration pathways.
