Multicopy Integration and Expression of Heterologous Genes in Methylobacterium extorquens ATCC 55366
BACKGROUND When organisms experience environmental change, how does their metabolic network reset and adapt to the new condition? Methylobacterium extorquens is a bacterium capable of growth on both multi- and single-carbon compounds. These different modes of growth utilize dramatically different central metabolic pathways with limited pathway overlap. METHODOLOGY/PRINCIPAL FINDINGS This stud...
In a previous paper, we reported identification of the 5' part of hprA of Methylobacterium extorquens AM1, which encodes the serine cycle enzyme hydroxypyruvate reductase (L. V. Chistoserdova and M. E. Lidstrom, J. Bacteriol. 174:71-77, 1992). Here we present the complete sequence of hprA and partial sequence of genes adjacent to hprA. Upstream of hprA, the 3' part of an open reading frame was ...
BACKGROUND Methylotrophy describes the ability of organisms to grow on reduced organic compounds without carbon-carbon bonds. The genomes of two pink-pigmented facultative methylotrophic bacteria of the Alpha-proteobacterial genus Methylobacterium, the reference species Methylobacterium extorquens strain AM1 and the dichloromethane-degrading strain DM4, were compared. METHODOLOGY/PRINCIPAL FI...
PhyR represents a novel alphaproteobacterial family of response regulators having a structure consisting of two domains; a predicted amino-terminal extracytoplasmic function (ECF) sigma factor-like domain and a carboxy-terminal receiver domain. PhyR was first described in Methylobacterium extorquens AM1, in which it has been shown to be essential for plant colonization, probably due to its sugg...
The DNA sequence for a 4.4-kb HindIII-XhoI Methylobacterium extorquens AM1 DNA fragment that is known to contain three genes (mxaAKL) involved in incorporation of calcium into methanol dehydrogenase (I. W. Richardson and C. Anthony, Biochem. J. 287:709-7115, 1992) was determined. Five complete open reading frames and two partial open reading frames were found, suggesting that this region contai...
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 ...
