The effect of lanthanum on growth and gene expression in a facultative methanotroph.

ABSTRACT: The biological importance of lanthanides has only recently been identified, initially as the active site metal of the alternative methanol dehydrogenase (MDH) Xox-MDH. So far, the effect of lanthanide (Ln) has only been studied in relatively few organisms. This work investigated the effects of Ln on gene transcription and protein expression in the facultative methanotroph Methylocella silvestris BL2, a widely distributed methane-oxidizing bacterium with the unique ability to grow not just on methane but also on other typical components of natural gas, ethane and propane. Expression of calcium- or Ln-dependent MDH was controlled by Ln (the lanthanide switch) during growth on one-, two- or three-carbon substrates, and Ln imparted a considerable advantage during growth on propane, a novel res
