Enzymatic conversion of D-glucose to D-fructose.
days against EDTA. Assuming a molecular weight for the virus of 50 x 106, calculation of the number of atoms of iron, copper, calcium, and magnesium per virus particle gave values of 20, 3, 52, and 45, respectively. The fact that iron and magnesium were concentrated approximately 20-fold in the virus ribonucleic acid compared with the occurrence of about 5 percent nucleic acid in the virus indi...
متن کاملEnzymatic Conversion of D-Glucose to D-Fructose Part I. Identification of Active Bacterial Strain and Confirmation of D-Fructose Formation
Enzymes which catalyze the interconversion of free aldopentose and ketopentose have been demonstrated in several bacterial strains. Concerning the conversion of free hexoses, however, the cases reported are few. Palleroni and Doudoroff1) described mannose isomerase in Pseudomonas saccharophila, which converted mannose to fructose. Marshall and Kooi2) then reported the ability of Pseudomonas hyd...

متن کاملD-fructose dehydrogenase of Gluconobacter industrius: purification, characterization, and application to enzymatic microdetermination of D-fructose.
D-Fructose dehydrogenase was solubilized and purified from the membrane fraction of glycerol-grown Gluconobacter industrius IFO 3260 by a procedure involving solubilization of the enzyme with Triton X-100 and subsequent fractionation on diethylaminoethyl-cellulose and hydroxylapatite columns. The purified enzyme was tightly bound to a c-type cytochrome and another peptide existing as a dehydrog...
متن کاملMelting behaviour of D-sucrose, D-glucose and D-fructose.
The melting behaviour of d-sucrose, d-glucose and d-fructose was studied. The melting peaks were determined with DSC and the start of decomposition was studied with TG at different rates of heating. In addition, melting points were determined with a melting point apparatus. The samples were identified as d-sucrose, alpha-d-glucopyranose and beta-d-fructopyranose by powder diffraction measuremen...
