Growth 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...

L-arabinose operon of Escherichia coli

TIG December 2000, volume 16, No. 12 559 Over forty years of research on the L-arabinose operon of Escherichia coli have provided insights into the mechanism of positive regulation of gene activity. This research also discovered DNA looping and the mechanism by which the regulatory protein changes its DNA-binding properties in response to the presence of arabinose. As is frequently seen in focu...

D-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...
