BACKGROUND Transport rates of long-chain free fatty acids into mitochondria via carnitine palmitoyltransferase I relative to overall oxidative rates in hypertrophied hearts remain poorly understood. Furthermore, the extent of glucose oxidation, despite increased glycolysis in hypertrophy, remains controversial. The present study explores potential compensatory mechanisms to sustain tricarboxyli...
1. The activities of 2-oxoglutarate dehydrogenase (EC 1.2.4.2) were measured in hearts and mammary glands of rats, mice, rabbits, guinea pigs, cows, sheep, goats and in the flight muscles of several Hymenoptera. 2. The activity of 2-oxoglutarate dehydrogenase was similar to the maximum flux through the tricarboxylic acid cycle in vivo. Therefore measuring the activity of this enzyme may provide...
Studies on the metabolism of the strict aerobe Micrococcus sodonensis revealed that a considerable accumulation of a-ketoglutarate and glutamate occurred. This accumulation was in evidence, both during growth on complex media and during growth on chemically defined media with acetate as the sole carbon source. The major pathway of terminal respiration in aerobically growing microorganisms appea...

For many years the importance of the Krebs tricarboxylic acid cycle in bacterial metabolism has been contested. Some authors find evidence for the occurrence of the cycle in certain species of bacteria; in other cases, results are interpreted as proving that the cycle does not operate (see Ajl for a recent review (1)). In most of these studies, as indeed with those on other organisms, the empha...
