Web6 apr. 2024 · The soluble methane monooxygenase (sMMO) is able to break the strong C−H bond of methane and convert it to methanol. The high structural complexity, multiplex cofactors, and unfamiliar folding or maturation procedures of sMMO have hampered the heterologous production and thus biotechnological applications. Web1 okt. 2006 · The soluble methane monooxygenase (sMMO) is a key enzyme for methane oxidation, and is found in only some methanotrophs, including Methylosinus sporium 5. sMMO expression is regulated at the level of transcription from a σ 54 promoter by a copper-switch, and is only expressed when the copper-to-biomass ratio during growth is low. …
