Novel dephosphotetrahydromethanopterin biosynthesis genes discovered via mutagenesis in Methylobacterium extorquens AM1.

ABSTRACT: 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.

Novel methylotrophy genes of Methylobacterium extorquens AM1 identified by using transposon mutagenesis including a putative dihydromethanopterin reductase.

Project description:Ten novel methylotrophy genes of the facultative methylotroph Methylobacterium extorquens AM1 were identified from a transposon mutagenesis screen. One of these genes encodes a product having identity with dihydrofolate reductase (DHFR). This mutant has a C(1)-defective and methanol-sensitive phenotype that has previously only been observed for strains defective in tetrahydromethanopterin (H(4)MPT)-dependent formaldehyde oxidation. These results suggest that this gene, dmrA, may encode dihydromethanopterin reductase, an activity analogous to that of DHFR that is required for the final step of H(4)MPT biosynthesis.

Glyoxylate regeneration pathway in the methylotroph Methylobacterium extorquens AM1.

Project description:Most serine cycle methylotrophic bacteria lack isocitrate lyase and convert acetyl coenzyme A (acetyl-CoA) to glyoxylate via a novel pathway thought to involve butyryl-CoA and propionyl-CoA as intermediates. In this study we have used a genome analysis approach followed by mutation to test a number of genes for involvement in this novel pathway. We show that methylmalonyl-CoA mutase, an R-specific crotonase, isobutyryl-CoA dehydrogenase, and a GTPase are involved in glyoxylate regeneration. We also monitored the fate of (14)C-labeled carbon originating from acetate, butyrate, or bicarbonate in mutants defective in glyoxylate regeneration and identified new potential intermediates in the pathway: ethylmalonyl-CoA, methylsuccinyl-CoA, isobutyryl-CoA, methacrylyl-CoA, and beta-hydroxyisobutyryl-CoA. A new scheme for the pathway is proposed based on these data.

Novel formaldehyde-activating enzyme in Methylobacterium extorquens AM1 required for growth on methanol.

Project description: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 found a previously unknown enzyme that efficiently catalyzes the removal of formaldehyde: it catalyzes the condensation of formaldehyde and tetrahydromethanopterin to methylene tetrahydromethanopterin, a reaction which also proceeds spontaneously, but at a lower rate than that of the enzyme-catalyzed reaction. Formaldehyde-activating enzyme (Fae) was purified from M. extorquens AM1 and found to be one of the major proteins in the cytoplasm. The encoding gene is located within a cluster of genes for enzymes involved in the further oxidation of methylene tetrahydromethanopterin to CO(2). Mutants of M. extorquens AM1 defective in Fae were able to grow on succinate but not on methanol and were much more sensitive toward methanol and formaldehyde. Uncharacterized orthologs to this enzyme are predicted to be encoded by uncharacterized genes from archaea, indicating that this type of enzyme occurs outside the methylotrophic bacteria.

Co-consumption of methanol and succinate by Methylobacterium extorquens AM1.

Project description: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-consumed, and the carbon conversion was two-thirds from succinate and one-third from methanol relative to mol carbon. (13)C-methanol labeling and liquid chromatography mass spectrometry analyses revealed the different fates of the carbon from the two substrates. Methanol was primarily oxidized to CO(2) for energy generation. However, a portion of the methanol entered biosynthetic reactions via reactions specific to the one-carbon carrier tetrahydrofolate. In contrast, succinate was primarily used to provide precursor metabolites for bulk biomass production. This work opens new perspectives on the role of methylotrophy when substrates are simultaneously available, a situation prevailing under environmental conditions.

Metabolic engineering of Methylobacterium extorquens AM1 for 1-butanol production.

Project description:BackgroundButanol 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-proteobacterium, is a model system for assessing the possibility of generating products such as 1-butanol from one-carbon and two-carbon feedstocks. Moreover, the core methylotrophic pathways in M. extorquens AM1 involve unusual coenzyme A (CoA)-derivative metabolites, such as crotonyl-CoA, which is a precursor for the production of 1-butanol.ResultsIn this work, we engineered a modified CoA-dependent pathway in Methylobacterium extorquens AM1 to produce 1-butanol. Engineered strains displayed different 1-butanol titers using ethylamine as a substrate. A strain overexpressing Treponema denticola trans-enoyl-CoA reductase, Clostridium acetobutylicum alcohol dehydrogenase, and native crotonase was able to generate the highest 1-butanol titer (15.2 mg l(-1)). In vitro isotopic tracing of metabolic flux and in vivo metabolite analysis showed the accumulation of butyryl-CoA, demonstrating the functionality of the synthetic pathway and identifying targets for future improvement.ConclusionsWe demonstrated the feasibility of using metabolic intermediates of the ethylmalonyl-CoA pathway in M. extorquens AM1 to generate value-added chemicals, with 1-butanol as the test case. This will not only establish the biotechnological potential of the ethylmalonyl-CoA pathway, but will also introduce M. extorquens AM1 as a potential platform to produce value-added chemicals.

Formaldehyde stress response in Methylobacterium extorquens AM1

Project description:The goal of this study was to use microarrays to identify genes differentially regulated under conditions of formaldehyde stress relative to two other stress conditions (oxidative, osmotic) in an effort to identify genes that might be involved in a formaldehyde-specific stress response, rather than a general stress response, in the model methylotroph Methylobacterium extorquens AM1. Two color experiment, three treatments, three biological replicates per treatment, and two technical (dye swap) replicates per biological replicate: formaldehyde-stressed vs. unstressed cells; oxidative-stressed vs. unstressed cells; and osmotic-stressed vs. unstressed cells.

Genetic organization of methylamine utilization genes from Methylobacterium extorquens AM1.

Project description:An isolated 5.2-kb fragment of Methylobacterium extorquens AM1 DNA was found to contain a gene cluster involved in methylamine utilization. Analysis of polypeptides synthesized in an Escherichia coli T7 expression system showed that five genes were present. Two of the genes encoded the large and small subunits of methylamine dehydrogenase, and a third encoded amicyanin, the presumed electron acceptor for methylamine dehydrogenase, but the function of the other two genes is not known. The order on the 5.2-kb fragment was found to be large-subunit gene, the two genes of unknown function, small-subunit gene, amicyanin gene. The gene for azurin, another possible electron acceptor in methylamine oxidation, does not appear to be present within this cluster of methylamine utilization genes.
