ACIDE SUCCINIQUE [10 records]

Record 1 2012-02-03

English

Subject field(s)
  • Biological Sciences
DEF

A constituent enzyme of the TCA cycle found in mitochondria of all aerobic cells. It contains FAD as a prosthetic group and requires no separate coenzyme. The enzyme catalyzes the formation of fumaric acid from succinic acid, coupled to the reduction of FAD.

French

Domaine(s)
  • Sciences biologiques
DEF

Enzyme catalysant la déshydrogénation du succinate en fumarate. Le système enzymatique le plus simple capable d’oxyder le succinate, en portant les hydrogènes sur un accepteur artificiel (phénazine-méthosulfate), a été isolé de membranes internes des mitochondries sous forme d’une ferroflavoprotéine à FAD et à fer non héminique.

CONT

L'inhibition compétitive existe pour tous les enzymes. Un analogue structural du substrat, non métabolisable, est en général un inhibiteur compétitif. On peut citer l'exemple de la succinodéshydrogénase, inhibée par divers analogues structuraux de l'acide succinique(qui n’ en diffèrent que par le nombre de maillons--CH2--compris entre les 2 groupements carboxyliques).

OBS

"Succinodéhydrase" est un terme vieilli à éviter.

Record 6 2003-01-31

English

Subject field(s)
  • Biochemistry
DEF

A type of fermentation carried out by members of the family Enterobacteriaceae in which ethanol and a complex mixture of organic acids are produced.

OBS

formic acid fermentation: In our view, this term is not a synonym of "mixed acid fermentation" but a specific. See the following context.

CONT

Methyl Red Voges Proskauer Test (MR-VP) - differentiates members of family Enterobacteriaciae based on ability to produce acid end products from fermentation of glucose. Enterobacteriaciae divided into two groups based on type of formic acid fermentation performed. 1.) Mixed acid type formic acid fermentation - results in production of ethanol and lactic, acetic, succinic, and formic acids as fermentation end products. If mixed acid fermentor, then when Methyl Red added to inoculated broth, medium turns red. If butanediol fermentor, then the color of the medium will change to yellow. Butanediol fermentor yields orange/yellow color after addition methyl red. 2.) Butanediol fermentors produce acidic fermentation products.

French

Domaine(s)
  • Biochimie
CONT

La fermentation acide mixte [...], réalisée par des entérobactéries, est caractérisée par la production d’éthanol et de plusieurs acides organiques :acide lactique, acide acétique, acide succinique, acide formique. Certaines bactéries(Escherichia coli) possèdent l'hydrogène lyase formique et décomposent immédiatement l'acide formique en hydrogène et gaz carbonique.
