Pentose metabolism in Mycobacterium smegmatis: comparison of L-arabinose isomerases induced by L-arabinose and D-galactose.
D-Galactose, which did not serve as a growth substrate, was found to induce an L-arabinose isomerase of similar properties to the L-arabinose-induced L-arabinose isomerase. In both cases the pH profiles, pH stability, optimum temperature, heat stability, substrate specificity, metal ion requirements, mobility on polyacrylamide gel electrophoresis, and kinetic properties of the induced isomerase...
متن کاملGrowth of Aerobacter aerogenes on D-arabinose and L-xylose.
Aerobacter aerogenes is noted for its versatility in being capable of growth by utilizing many of the rare and unnatural carbohydrates as substrates. The mechanism of growth on several of these unnatural carbohydrates has been previously reported. A. aerogenes PRL-R3 possesses the ability to synthesize, in response to the common substrate ribitol, a ribitol dehydrogenase which will also catalyz...
متن کاملEffects of Insulin on the Permeability of D- and L-Xylose and D- and L-Arabinose in Rat Diaphragm Muscle
The permeability characteristics of D- and L-xylose and D- and L-arabinose have been compared in isolated intact rat diaphragm muscle preparations, in the absence and presence of exogenous insulin. In the absence of added insulin, these pentoses distribute in less than a third of the total cell water. In the presence of added insulin, intracellular distribution of all these pentoses is increase...
متن کاملD-arabinose metabolism in Escherichia coli B: induction and cotransductional mapping of the L-fucose-D-arabinose pathway enzymes.
D-Arabinose is degraded by Escherichia coli B via some of the L-fucose pathway enzymes and a D-ribulokinase which is distinct from the L-fuculokinase of the L-fucose pathway. We found that L-fucose and D-arabinose acted as the apparent inducers of the enzymes needed for their degradation. These enzymes, including D-ribulokinase, appeared to be coordinately regulated, and mutants which constitut...
