Genetic organization of methylamine utilization genes from Methylobacterium extorquens AM1.
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 ac...
متن کاملThe small-subunit polypeptide of methylamine dehydrogenase from Methylobacterium extorquens AM1 has an unusual leader sequence.
The nucleotide sequence for the N-terminal region of the small subunit of methylamine dehydrogenase from Methylobacterium extorquens AM1 has revealed a leader sequence that is unusual in both its length and composition. Gene fusions to lacZ and phoA show that this leader sequence does not function in Escherichia coli but does function in M. extorquens AM1.
متن کاملIdentification and nucleotide sequences of mxaA, mxaC, mxaK, mxaL, and mxaD genes from Methylobacterium extorquens AM1.
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...
متن کاملCrystallographic and spectroscopic studies of native, aminoquinol, and monovalent cation-bound forms of methylamine dehydrogenase from Methylobacterium extorquens AM1.
Various monovalent cations influence the enzymatic activity and the spectroscopic properties of methylamine dehydrogenase (MADH). Here, we report the structure determination of this tryptophan tryptophylquinone-containing enzyme from Methylobacterium extorquens AM1 by high resolution x-ray crystallography (1.75 A). This first MADH crystal structure at low ionic strength is compared with the hig...
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...
