Sodium dodecyl sulphate electrophoresis of wheat gliadins.
Polypeptide chain weights of a-, 8and y-gliadin fractions have been estimated by polyacrylamide gel electrophoresis in the presence of mercaptoethanol and sodium dodecyl sulphate. Values lie in the range 32 000 to 44 OOO. When available data on the amino acid analyses were adjusted and compared, significant similarities emerged. It is suggested that these gliadins contain a minimum of 4 cystine...
متن کاملMobility of sodium dodecyl sulphate - protein complexes.
Reduced and unreduced lysozyme aggregates formed by formaldehyde cross-linking comprise a set of model compounds for studying the effects of protein conformation on the electrophoretic mobilities of sodium dodecyl sulphate-protein complexes. The reduced aggregates were indistinguisable from normal proteins, but the unreduced aggregates migrated anomalously fast by about 14%. Contrary to expecta...
متن کاملThe dissociation of glucose oxidase by sodium n-dodecyl sulphate.
1. The enzymic activity of glucose oxidase was determined as a function of pH and sodium n-dodecyl sulphate (SDS) concentration. 2. Glucose oxidase is not deactivated by SDS at pH 6 even after prolonged incubation, but is deactivated at pH 4.3 and 3.65. 3. Sedimentation-rate analysis showed that glucose oxidase dissociates into its two subunits at pH 5 and below, and sedimentation-equilibrium e...
متن کاملAnaerobic degradation of pimelate by newly isolated denitrifying bacteria.
A C7 dicarboxylic (pimelic) acid derivative is postulated as an intermediate in anaerobic degradation of benzoate. Four strains of Gram-negative, nitrate-reducing bacteria capable of growth with both pimelate and benzoate as sole carbon and energy source were isolated. The metabolism of strain LP-1, which was enriched from activated sludge with pimelate as substrate, was studied in detail. This...
متن کاملAnaerobic degradation of 2-aminobenzoate (anthranilic acid) by denitrifying bacteria.
In the presence of oxygen many aminoaromatic compounds polymerize to form recalcitrant macromolecules. To circumvent undesirable oxidation reactions, the anaerobic biodegradation of a simple member of this class of compounds was investigated. Two strains of bacteria were isolated which degrade 2-aminobenzoate anaerobically under denitrifying conditions, with nitrate as the terminal electron acc...
