When succinate dehydrogenase contains oxalacetate in firmly bound form, activity cannof the enzyme results in dissociation of oxalacetate and activation of the enzyme. The course of reductive titrations appears the same whether or not the enzyme cont

From a study of the magnetic field dependence of the linear electric field effect (LEFE) in EPR spectroscopy, we demonstrate that iron-sulfur cluster 3 in air-oxidized, beef heart succinate-ubiquinone oxidoreductase (Complex II) is a 3-iron cluster.

Existing procedures for the isolation of mammalian succinate dehydrogenase yield preparations of high purity or retain reconstitution activity, but not both. A new procedure is described for the isolation in good yield of virtually homogeneous prepar

Riboflavine uptake and membrane-associated riboflavin-binding activity has been investigated in Bacillus subtilis. Riboflavin uptake proceeds via a system whose general properties are indicative of a carrier-mediated process: it is inhibited by subst

Electron paramagnetic resonance studies of Complex II from the mitochondrial respiratory chain and soluble preparations of succinate dehydrogenase have, for the first time, identified a signal arising from a [4Fe-4S]1+ cluster, S2, in dithionite-redu

A flavokinase preparation from Bacillus subtilis is described which catalyzes the phosphorylation of reduced, but not oxidized, riboflavin. The enzyme is distinguished from other known flavokinases also in having an unusually low Km for the flavin su

The effects of iron deficiency on the NADH- and succinate-oxidizing complexes of rat skeletal muscle mitochondria have been investigated. Both systems were similarly affected: activities were about 30% of normal in dehydrogenase, ubiquinone reductase

The turnover number of succinate dehydrogenase from mammalian heart determined by the spectrophotometric phenazine methosulfate assay, after complete activation, is approximately 21,000 mol of succinate oxidized/min/mol of histidyl flavin at 38 degre
