Diversity and distribution of the lanthanome in aerobic methane-oxidising bacteria [PDF]

Environmental Microbiome
Background Lanthanides (Ln) play important and often regulatory roles in the metabolism of methylotrophs, including methanotrophs, particularly through their involvement in methanol oxidation.

Identification of a TonB-Dependent Receptor Involved in Lanthanide Switch by the Characterization of Laboratory-Adapted Methylosinus trichosporium OB3b. [PDF]

Appl Environ Microbiol, 2023
Lanthanides are widely used in many industrial applications, including catalysts, magnets, and polishing. Recently, lanthanide-dependent metabolism was characterized in methane-utilizing bacteria.

Weathered granites and soils harbour microbes with lanthanide-dependent methylotrophic enzymes [PDF]

BMC Biology
Background Prior to soil formation, phosphate liberated by rock weathering is often sequestered into highly insoluble lanthanide phosphate minerals. Dissolution of these minerals releases phosphate and lanthanides to the biosphere.

Light Rare Earth Element Depletion During Deepwater Horizon Blowout Methanotrophy [PDF]

Scientific Reports, 2017
Rare earth elements have generally not been thought to have a biological role. However, recent work has demonstrated that the light REEs (LREEs: La, Ce, Pr, and Nd) are essential for at least some methanotrophs, being co-factors in the XoxF type of ...

Modulation of carbon-to-nitrogen ratio shapes the microbial ecology in a methanol-fed recirculating marine denitrifying reactor [PDF]

PeerJ
Background Nitrate (NO3−) can accumulate in closed-circuit ecosystems to a toxic level. Adding heterotrophic denitrification process to the water treatment is a strategy to reduce this level. This type of process usually requires the addition of a carbon

Natural Selection in Synthetic Communities Highlights the Roles of Methylococcaceae and Methylophilaceae and Suggests Differential Roles for Alternative Methanol Dehydrogenases in Methane Consumption

Frontiers in Microbiology, 2017
We describe experiments that follow species dynamics and gene expression patterns in synthetic bacterial communities including species that compete for the single carbon substrate supplied, methane, and species unable to consume methane, which could only

Genomic Evidence for Simultaneous Optimization of Transcription and Translation through Codon Variants in the pmoCAB Operon of Type Ia Methanotrophs [PDF]

mSystems, 2019
Understanding the interplay between genotype and phenotype is a fundamental goal of functional genomics. Methane oxidation is a microbial phenotype with global-scale significance as part of the carbon biogeochemical cycle and a sink for greenhouse gas ...

Extensive and diverse lanthanide-dependent metabolism in the ocean. [PDF]

ISME J
To date, the only known Lanthanide (Ln)-dependent enzymes are pyrroloquinoline quinone-dependent alcohol dehydrogenases. When compared to their Ca dependent counterparts, there is an emerging picture that Ln-dependent versions of these enzymes are ...

XoxF Acts as the Predominant Methanol Dehydrogenase in the Type I Methanotroph Methylomicrobium buryatense [PDF]

Journal of Bacteriology, 2016
ABSTRACT Many methylotrophic taxa harbor two distinct methanol dehydrogenase (MDH) systems for oxidizing methanol to formaldehyde: the well-studied calcium-dependent MxaFI type and the more recently discovered lanthanide-containing XoxF type.

Functional investigation of methanol dehydrogenase-like protein XoxF in Methylobacterium extorquens AM1. [PDF]

Microbiology, 2010
Methanol dehydrogenase-like protein XoxF of Methylobacterium extorquens AM1 exhibits a sequence identity of 50 % to the catalytic subunit MxaF of periplasmic methanol dehydrogenase in the same organism. The latter has been characterized in detail, identified as a pyrroloquinoline quinone (PQQ)-dependent protein, and shown to be essential for growth in ...
