The first gene cluster encoding for a membrane bound [NiFe] hydrogenase from a methanotroph, Methylococcus capsulatus (Bath), was cloned and sequenced. The cluster consisted of the structural genes hupS and hupL and accessory genes hupE, hupC and hupD. A ΔhupSL deletion mutant of Mc. capsulatus was constructed by marker exchange mutagenesis. Membrane associated hydrogenase activity disappeared. The membrane associated hydrogenase appeared to have a hydrogen uptake function in vivo.
