Glyoxylate regeneration pathway in the methylotroph Methylobacterium extorquens AM1.
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-speci...
متن کاملMetabolic 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 کاملAlternative route for glyoxylate consumption during growth on two-carbon compounds by Methylobacterium extorquens AM1.
Methylobacterium extorquens AM1 is a facultative methylotroph capable of growth on both single-carbon and multicarbon compounds. Mutants defective in a pathway involved in converting acetyl-coenzyme A (CoA) to glyoxylate (the ethylmalonyl-CoA pathway) are unable to grow on both C(1) and C(2) compounds, showing that both modes of growth have this pathway in common. However, growth on C(2) compou...
متن کاملThe ethylmalonyl-CoA pathway is used in place of the glyoxylate cycle by Methylobacterium extorquens AM1 during growth on acetate.
Acetyl-CoA assimilation was extensively studied in organisms harboring the glyoxylate cycle. In this study, we analyzed the metabolism of the facultative methylotroph Methylobacterium extorquens AM1, which lacks isocitrate lyase, the key enzyme in the glyoxylate cycle, during growth on acetate. MS/MS-based proteomic analysis revealed that the protein repertoire of M. extorquens AM1 grown on ace...
متن کاملIdentification of genes involved in the glyoxylate regeneration cycle in Methylobacterium extorquens AM1, including two new genes, meaC and meaD.
The glyoxylate regeneration cycle (GRC) operates in serine cycle methylotrophs to effect the net conversion of acetyl coenzyme A to glyoxylate. Mutants have been generated in several genes involved in the GRC, and phenotypic analysis has been carried out to clarify their role in this cycle.
