Metabolism of D-fructose by Arthrobacter pyridinolis.
Previous studies showed that Arthrobacter pyridinolis can transport and utilize d-glucose only after prior growth on certain Krebs cycle intermediates. In contrast, we found that d-fructose was taken up and metabolized by A. pyridinolis without special prior conditions of growth. d-Fructose was first converted to d-fructose-1-phosphate by a phosphoenolpyruvate (PEP):D-fructose phosphotransferas...
متن کاملMetabolism of L-rhamnose by Escherichia coli. I. L-rhamnose isomerase.
The methyl pentose, L-rhamnose, is known to be fermented by a number of bacteria, but little information is available concerning the metabolic steps involved in this fermentation. An indication of the pathway of rhamnose metabolism was provided by the finding of Kluyver and Schnellen (1937) that propylene glycol was a major product in the fermentation by Bacillus rhamnosifermentans. Since 50 pe...
متن کاملMetabolism of L-fucose and L-rhamnose in Escherichia coli: aerobic-anaerobic regulation of L-lactaldehyde dissimilation.
L-Lactaldehyde is a branching point in the metabolic pathway of L-fucose and L-rhamnose utilization. Under aerobic conditions, L-lactaldehyde is oxidized to L-lactate by the enzyme lactaldehyde dehydrogenase, while under anaerobic conditions, L-lactaldehyde is reduced to L-1,2-propanediol by the enzyme propanediol oxidoreductase. Aerobic growth on either of the methyl pentoses induces a lactald...
متن کاملL-Rhamnose increases serum propionate in humans.
BACKGROUND Acetic and propionic acids are produced by colonic bacterial fermentation of unabsorbed carbohydrates and are absorbed into the portal circulation. From there, they travel to the liver, where acetate is a lipogenic substrate and propionate can inhibit lipogenesis. The extent to which peripheral blood short-chain fatty acid concentrations reflect differences in colonic fermentation is...
متن کاملBacterial dissimilation of L-fucose and L-rhamnose.
Eagon, R. G. (University of Georgia, Athens). Bacterial dissimilation of l-fucose and l-rhamnose. J. Bacteriol. 82:548-550. 1961.-Of 33 microorganisms screened for the ability to utilize the methylpentoses, l-fucose and l-rhamnose, 18 species utilized one or both methylpentoses. The majority of the bacterial species capable of utilizing these methylpentoses did so by isomerization of the methyl...
