ISOCITRIC DEHYDROGENASE IN GREEN LEAVES

Triphosphopyridine nucleotide linked isocitric dehydrogenase in bacteria.

The conversion of isocitric acid to alpha-ketoglutarate has been demonstrated both in animal tissues (Martius, 1937; Krebs and Johnson, 1937; Adler et al., 1939; Ochoa, 1948) and in yeast (Kornberg and Pricer, 1951; Foulkes, 1951). Triphosphopyridine nucleotide was first implicated as a specific coenzyme for this reaction by Adler et al. (1939). Recently Kornberg and Pricer (1951) found in yeas...

Serum transaminases and isocitric dehydrogenase in kwashiorkor.

Serum glutamic oxalacetic transaminase (G-OT), glutamic-pyruvic transaminase (G-PT), and isocitric dehydrogenase (ICD) have been estimated in six groups of subjects, namely, normal British adults, normal Nigerian adults, undernourished Nigerian adults and children, Nigerian children with florid protein malnutrition (kwashiorkor), and cases of protein malnutrition after treatment. The normal ran...

Enzyme systems in the mycobacteria. I. The isocitric dehydrogenase.

D-Isocitric acid

Mix**, wait for the end of the reaction (approx. 10 min) and read the absorbances of the solutions (A2). If the reaction has not stopped after 10 min, continue to read the absorbances at 2 min intervals until the absorbance increases constantly over 2 min. Determine the absorbance differences (A2-A1) for both, blank and sample. Subtract the absorbance difference of the blank from the absorbance...
