Studies on Succinate Dehydrogenase
1. Succinate dehydrogenase flavocoenzyme (“SD-flavin”), previously shown to be an SOLsubstituted riboflavin derivative containing a tertiary nitrogen homoconjugated to the flavin nucleus, was subjected to further hydrolysis and to reduction under acid conditions. Both conditions resulted in the liberation of 1 mole of histidine per mole of flavin. This proves histidine to be the covalent link b...
متن کاملStudies on the binding of carboxin analogs to succinate dehydrogenase.
Carboxin (5,6-dihydro-2-methyl-l,4-oxathiin-3-carboxanilide) and a number of other carboxanilides are known to be potent inhibitors of succinate oxidation in membrane preparations from animal tissues, fungi, and bacteria, acting at the succinate dehydrogenase-coenzyme Q junction. The kinetics and the maximal extent of inhibition of succinate oxidation by carboxanilides and by thenoyltrifluoroac...
متن کاملDiminished inhibition of mitochondrial electron transfer from succinate to cytochrome c by thenoyltrifluoroacetone induced by antimycin.
Thenoyltrifluoroacetone inhibits succinate-cytochrome c reductase activity of resolved succinate*cytochrome c reductase complex. Dixon plots of [succinate-cytochrome c reductase activity]-’ or [succinateubiquinone reductase activity]-’ versus concentration of inhibitor are consistent with there being a single site of inhibition by thenoyltrifluoroacetone in resolved reductase complex. This agre...

1. to determine whether difference in birth body mass influenced growth performance in pipistrellus kuhlii we studied a total of 12 captive-born neonates. bats were assigned to two body mass groups: light birth body mass (lbw: 0.89 ± 0.05, n=8) and heavy birth body mass (hbw: 1.35 ± 0.08, n=4). heavier body mass at birth was associated with rapid postnatal growth (body mass and forearm length) ...
