Methanol Assimilation in Methylobacterium extorquens AM1: Demonstration of All Enzymes and Their Regulation
BACKGROUND Methylobacterium extorquens AM1 is an aerobic facultative methylotrophic α-proteobacterium that can use reduced one-carbon compounds such as methanol, but also multi-carbon substrates like acetate (C₂) or succinate (C₄) as sole carbon and energy source. The organism has gained interest as future biotechnological production platform based on methanol as feedstock. METHODOLOGY/PRINCI...
متن کاملCo-Consumption of Methanol and Succinate by Methylobacterium extorquens AM1
Methylobacterium extorquens AM1 is a facultative methylotrophic Alphaproteobacterium and has been subject to intense study under pure methylotrophic as well as pure heterotrophic growth conditions in the past. Here, we investigated the metabolism of M. extorquens AM1 under mixed substrate conditions, i.e., in the presence of methanol plus succinate. We found that both substrates were co-consume...
متن کاملThe second subunit of methanol dehydrogenase of Methylobacterium extorquens AM1.
The nucleotide and deduced amino acid sequence of a novel small (beta) subunit of methanol dehydrogenase of Methylobacterium extorquens AM1 (previously Pseudomonas AM1) has been determined. Work with the whole protein has shown that is has an alpha 2 beta 2 configuration.
متن کاملFunctional investigation of methanol dehydrogenase-like protein XoxF in Methylobacterium extorquens AM1.
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 the presence of methanol in this methylotro...
متن کاملA Catalytic Role of XoxF1 as La3+-Dependent Methanol Dehydrogenase in Methylobacterium extorquens Strain AM1
In the methylotrophic bacterium Methylobacterium extorquens strain AM1, MxaF, a Ca(2+)-dependent methanol dehydrogenase (MDH), is the main enzyme catalyzing methanol oxidation during growth on methanol. The genome of strain AM1 contains another MDH gene homologue, xoxF1, whose function in methanol metabolism has remained unclear. In this work, we show that XoxF1 also functions as an MDH and is ...
