Lanthanide-dependent methanol dehydrogenase

UniProtKB accession:  C5B120

Grouped By:  Matching UniProtKB accession

UniProtKB description:  Catalyzes the oxidation of methanol to formaldehyde, but only in the presence of lanthanides (Ln). Contributes to methanol metabolism when La(3+) is present in the natural environment of the bacterium, allowing bacterial growth with methanol as carbon and energy source. Thereby is an essential enzyme for Ln-dependent methylotrophy (PubMed:23209751, PubMed:30862918, PubMed:32366463). Uses a specific cytochrome cL (XoxG), encoded by the adjacent gene in the locus, as electron acceptor (Probable). Also plays a role in the transcriptional regulation of the mxa and xox1 operons, most likely acting as a lanthanide sensory module (PubMed:32366463). Is also able to oxidize formaldehyde to formate in vitro, but this activity does not occur in vivo (PubMed:30862918).
