Production of an insecticidal crystal protein from Bacillus thuringiensis by the methylotroph Methylobacterium extorquens.
The Cry1Aa protein from Bacillus thuringiensis is an insecticidal protein that is highly active against several species of Lepidoptera. We cloned and expressed the cry1Aa gene in a plant-colonizing methylotroph, Methylobacterium extorquens, under the control of the strong M. extorquens AM1 methanol dehydrogenase promoter, P(mxaF). Transmission electron microscopy revealed characteristic bipyram...
متن کاملGlyoxylate 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 کاملdehydrogenase from Methylobacterium extorquens
The structure of methanol dehydrogenase (MDH) at 0.194 nm (1.94 A) has been used to provide a model structure for part of a membrane quinoprotein glucose dehydrogenase (GDH). The basic superbarrel structure is retained, along with the tryptophandocking motifs. The active-site regions are similar, but there are important differences, the most important being that GDH lacks the novel disulphide r...
متن کاملPurification and Characterization of Hydroxypyruvate Reductase from the Facultative Methylotroph Methylobacterium extorquens AMI
Hydroxypyruvate reductase was purified to homogeneity from the facultative methylotroph Methylobacterium extorquens AM1. It has a molecular mass of about 71 kDa, and it consists of two identical subunits with a molecular mass of about 37 kDa. This enzyme uses both NADH (Km = 0.04 mM) and NADPH (Km = 0.06 mM) as cofactors, uses hydroxypyruvate (Km = 0.1 mM) and glyoxylate (Km = 1.5 mM) as the on...
متن کاملComplete Genome Sequence of the Facultative Methylotroph Methylobacterium extorquens TK 0001 Isolated from Soil in Poland
Methylobacterium extorquens TK 0001 (DSM 1337, ATCC 43645) is an aerobic pink-pigmented facultative methylotrophic alphaproteobacterium isolated from soil in Poland. Here, we report the whole-genome sequence and annotation of this organism, which consists of a single 5.71-Mb chromosome.
