Succinate Dehydrogenase is the Regulator of Respiration in Mycobacterium tuberculosis
In chronic infection, Mycobacterium tuberculosis bacilli are thought to enter a metabolic program that provides sufficient energy for maintenance of the protonmotive force, but is insufficient to meet the demands of cellular growth. We sought to understand this metabolic downshift genetically by targeting succinate dehydrogenase, the enzyme which couples the growth processes controlled by the T...
متن کاملStudies 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 کاملSDH5, a gene required for flavination of succinate dehydrogenase, is mutated in paraganglioma.
Mammalian mitochondria contain about 1100 proteins, nearly 300 of which are uncharacterized. Given the well-established role of mitochondrial defects in human disease, functional characterization of these proteins may shed new light on disease mechanisms. Starting with yeast as a model system, we investigated an uncharacterized but highly conserved mitochondrial protein (named here Sdh5). Both ...
متن کاملSuccinate Dehydrogenase Deficiency Is Rare in Pituitary Adenomas
Germline mutations in the succinate dehydrogenase genes (SDHA, SDHB, SDHC, and SDHD) are established as causes of pheochromocytoma/paraganglioma, renal carcinoma, and gastrointestinal stromal tumor. It has recently been suggested that pituitary adenomas may also be a component of this syndrome. We sought to determine the incidence of SDH mutation in pituitary adenomas. We performed screening im...
متن کاملSingle motoneuron succinate dehydrogenase activity.
We have developed a quantitative histochemical assay for measurement of succinate dehydrogenase (SDH) activity in single motoneurons. A computer image processing system was used to quantify the histochemical enzyme reaction product and to follow the time course of the reaction. The optimal concentration for each of the ingredients of the incubation medium for the SDH reaction was determined and...
