Ubiquinol Oxidase in Acetobacter aceti
The terminal oxidase for ethanol oxidation in Acetobacter aced was purified as a complex consisting of four subunits (subunits I, II, III, and IV) with molecular masses of 72, 34, 21, and 13 kDa, respectively. Spectrophotometric analysis and catalytic properties determined with the purified enzyme showed that it belonged to a family of cytochrome a, (ba)-type ubiquinol oxidases. A polymerase ch...
متن کاملSynthesis of Cellulose by Acetobacter Xylinum
Appearance of cellulose microfibrils in the medium of a suspension of cells of Acetobacter xylinum in buffered glucose solution was preceded by a stage during which the cellulose in the medium was amorphous within the available resolution. The size of the vertical axis of the microfibrils of the bacterial cellulose was found on the basis of measurement of shadow length to be only about 16 A. In...
متن کاملMetabolism of Dicarboxylic Acids in Acetobacter Xylinum.
Benziman, Moshe (The Hebrew University of Jerusalem, Jerusalem, Israel), and A. Abeliovitz. Metabolism of dicarboxylic acids in Acetobacter xylinum. J. Bacteriol. 87:270-277. 1964.-During the oxidation of fumarate or l-malate by whole cells or extracts of Acetobacter xylinum grown on succinate, a keto acid accumulated in the medium in considerable amounts. This acid was identified as oxaloaceti...
متن کاملBreeding of a 5-Fluorouridine-resistant Mutant with Increased Cellulose Production from Acetobacter xylinum subsp. nonacetoxidans.
UDP-glucose (UDP-G), the direct precursor of cellulose, is known to be produced from UTP and glucose-1-phosphate. In an attempt to increase UTP biosynthesis, 5-fluorouridine (5-FUR: a pyrimidine analog)-resistant mutants were obtained using Acetobacter xylinum subsp. nonacetoxidans 757 as the parent strain. One of the 5-FUR-resistant mutants, FUR-35, showed about 40% higher cellulose productivi...
متن کاملEncoding Cellulolytic Activity in Acetobacter xylinum
Recently, it was shown that a cellulose-negative mutant (Cell) ofAcetobacterxylinum ATCC 23769 carried an insertion of an indigenous transposable element (IS1031A) about 500 bp upstream of the bcs operon, required for cellulose synthesis. Here we show that Cell can be complemented by wild-type DNA covering the insertion point. Nucleotide sequencing of this region revealed the presence of two op...
