Final Stage in the Biological Oxidation Processes: Krebs' Tricarboxylic Cycle

Malonate inhibition of oxidations in the Krebs tricarboxylic acid cycle.

The inhibition of succinate oxidation by malonate is a well known phenomenon. Since the oxidation of succinate to fumarate is an integral part of the Krebs cycle of oxidations, it has been generally assumed that the inhibitory effect of malonate upon the oxidation of any member of the cycle is the result of the inhibition of the succinate to fumarate step. However, the present paper provides ev...

The oxidation of tricarboxylic acid cycle compounds by Penicillium chrysogenum.

The presence of a tricarboxylic acid cycle in Penicillium chry8ogenum, as yet, has not been demonstrated conclusively. Ajl (1951) stated that of the mechanisms proposed for oxidation of the 2 carbon fragment in mold metabolism, the evidence for a tricarboxylic acid cycle is the least convincing. This paper presents a study of some of the enzymes of the tricarboxylic acid cycle in cell-free prep...

The Tricarboxylic Acid Cycle in Dictyostelium discoideum

Some aspects of tricarboxylic acid-cycle activity during differentiation and aging in Dictyostelium discoideum were examined. The concentrations of glutamate, aspartate, alanine, citrate, 2-oxoglutarate, succinate, fumarate, malate, oxaloacetate, pyruvate and acetyl-CoA were determined at four stages over the course of differentiation. The rate of 02 utilization was also determined over differe...
