Diversity in butane monooxygenases among butane-grown bacteria.
Butane monooxygenases of butane-grown Pseudomonas butanovora, Mycobacterium vaccae JOB5, and an environmental isolate, CF8, were compared at the physiological level. The presence of butane monooxygenases in these bacteria was indicated by the following results. (i) O(2) was required for butane degradation. (ii) 1-Butanol was produced during butane degradation. (iii) Acetylene inhibited both but...
متن کاملButane-1,4-diammonium hexafluorosilicate
The title compound, [NH3(CH2)4NH3](2+)·SiF6 (2-), is a hybrid built from an organic butane-1,4-di-ammonium dication linked to a hexa-fluoro-silicate mineral anion. Both ions posses inversion symmetry. In the anion the Si atom is located on an inversion center, while in the cation the center of inversion is situated at the mid-point of the central -CH2-CH2- bond. The Si atom is surrounded by six...
متن کاملButane-1,2,3,4-tetracarboxylic acid dihydrate
The asymmetric unit of the title compound, C(8)H(10)O(8)·2H(2)O, contains one half-mol-ecule of butane-1,2,3,4-tetra-carboxylic acid and a water mol-ecule, with the complete tetra-acid generated by crystallographic inversion symmetry. Inter-molecular O-H⋯O hydrogen bonds form an extensive three-dimensional network, which consolidates the crystal packing.
متن کاملButane-1,4-diammonium bis(perchlorate)
The butane-1,4-diammonium cation of the title compound, C(4)H(14)N(2) (2+)·2ClO(4) (-), lies on a special position of site symmetry 2/m, whereas the perchlorate anion is located on a crystallographic mirror plane. An intricate three-dimensional hydrogen-bonding network exists in the crystal structure with each H atom of the ammonium group exhibiting bifurcated inter-actions to the perchlorate a...
متن کامل1,4-Bis(2-nitrophenoxy)butane
The asymmetric unit of the title compound, C(16)H(16)N(2)O(6), contains one-half mol-ecule, the mid-point of the central C-C bond being located on a crystallographic inversion center. The crystal structure shows weak inter-actions between the O atoms of the nitro groups and two different C-H groups of the benzene rings. The extended weak hydrogen-bond formation, involving the NO(2) groups, gene...
