Metabolic engineering of Methylobacterium extorquens AM1 for 1-butanol production
BACKGROUND Butanol is a promising next generation fuel and a bulk chemical precursor. Although clostridia are the primary industrial microbes for the fermentative production of 1-butanol, alternative engineered hosts have the potential to generate 1-butanol from alternative carbon feedstocks via synthetic metabolic pathways. Methylobacterium extorquens AM1, a facultative methylotrophic α-proteo...
متن کاملNovel formaldehyde-activating enzyme in Methylobacterium extorquens AM1 required for growth on methanol.
Formaldehyde is toxic for all organisms from bacteria to humans due to its reactivity with biological macromolecules. Organisms that grow aerobically on single-carbon compounds such as methanol and methane face a special challenge in this regard because formaldehyde is a central metabolic intermediate during methylotrophic growth. In the alpha-proteobacterium Methylobacterium extorquens AM1, we...
متن کاملBiochemical characterization of a dihydromethanopterin reductase involved in tetrahydromethanopterin biosynthesis in Methylobacterium extorquens AM1.
During growth on one-carbon (C1) compounds, the aerobic alpha-proteobacterium Methylobacterium extorquens AM1 synthesizes the tetrahydromethanopterin (H4MPT) derivative dephospho-H4MPT as a C1 carrier in addition to tetrahydrofolate. The enzymes involved in dephospho-H4MPT biosynthesis have not been identified in bacteria. In archaea, the final step in the proposed pathway of H4MPT biosynthesis...
متن کاملNovel dephosphotetrahydromethanopterin biosynthesis genes discovered via mutagenesis in Methylobacterium extorquens AM1.
Methylobacterium extorquens AM1 was used to explore the genetics of dephosphotetrahydromethanopterin (dH(4)MPT) biosynthesis. Strains with mutations in eight "archaeal-type" genes linked on the chromosome of M. extorquens AM1 were analyzed for the ability to synthesize dH(4)MPT, and six were found to be dH(4)MPT negative. Putative functions of these genes in dH(4)MPT biosynthesis are discussed.
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.
