The DNA sequence of the structural gene for glucose dehydrogenase (EC 18.104.22.168) of Bacillus subtilis was determined and comprises 780 base pairs. The subunit molecular weight of glucose dehydrogenase as deduced from the nucleotide sequence is 28,196, which agrees well with the subunit molecular weight of 31,500 as determined from sodium dodecyl… (More)
Inositol 2-dehydrogenase (EC 22.214.171.124) activity appears during growth of Bacillus subtilis (strain 60015) in nutrient sporulation medium. Its synthesis is induced by myo-inositol and repressed by D-glucose. The enzyme has an apparent molecular weight of 155,000 to 160,000 as determined by sucrose density gradient centrifugation, and it is comprised of four… (More)
A thermophilic (70 C), gram-negative bacterium has been isolated that resembles Thermus aquaticus but lacks the type-characteristic yellow carotenoid.
Late during sporulation, Bacillus subtilis produces glucose dehydrogenase (GlcDH; EC 126.96.36.199), which can react with D-glucose or 2-deoxy-D-glucose and can use nicotinamide adenine dinucleotide (NAD) or nicotinamide adenine dinucleotide phosphate (NADP) as a cofactor. This enzyme is found mainly in the forespore compartment and is present in spores; it is… (More)
Streptavidin is an extracellular tetrameric protein produced by Streptomyces avidinii. A series of hybrid gene fusions consisting of Bacillus signal peptide coding regions fused to the mature streptavidin sequence were constructed. B. subtilis strains harboring these plasmids accumulate a tetrameric streptavidin in the growth medium. The properties of the… (More)
Here we present the genome of strain Exiguobacterium sp. AT1b, a thermophilic member of the genus Exiguobacterium whose representatives were isolated from various environments along a thermal and physicochemical gradient. This genome was sequenced to be a comparative resource for the study of thermal adaptation with a psychroactive representative of the… (More)
Histidine decarboxylase, the synthetic enzyme for histamine, was partially purified from regions of rat or rabbit brain rich in the enzyme. The enzyme was purified using ion exchange and hydrophobic column chromatography and chromatofocusing. Approximately 70-fold and 110-fold enrichments were attained from rat and rabbit brain, respectively. Rat and rabbit… (More)
The fatty acid composition of a recently isolated, extreme thermophilic bacterium of the genus Thermus has been determined and has been shown to be significantly different from that of Thermus aquaticus YT-1 when the two bacteria were grown under the same cultural conditions.
Bacillus subtilis glucose dehydrogenase (EC 188.8.131.52) has been purified from sporulating cell extract to apparent homogeneity (as determined by polyacrylamide gel electrophoresis, sodium dodecyl sulfate-polyacrylamide gel electrophoresis, and isoelectric focusing). The enzyme purified as a single molecular species with no evidence for a multiple form of the… (More)
