ISOMERASA [3 records]

Record 1 2012-09-14

English

Subject field(s)
  • Biochemistry
DEF

An intracellular enzyme which converts D-glucose to D-fructose, although its main function in vivo is probably the conversion of D-xylose to D-xylulose; the enzyme is typically induced in the presence of xylose.

French

Domaine(s)
  • Biochimie
DEF

Enzyme d'origine bactérienne qui transforme le glucose en fructose; on la fait travailler sous une forme immobilisée (enzymes ou microorganismes fixés) en continu sur un support inorganique, dans l'industrie de l'amidonnerie.

Spanish

Campo(s) temático(s)
  • Bioquímica
DEF

Enzima que cataliza la interconversión de los dos azúcares glucosa y fructosa.

OBS

Como la fructosa es un compuesto de menor energía que la glucosa, una mezcla de glucosa, fructosa y la enzima terminará por contener casi totalmente el azúcar en forma de fructosa.

Record 2 2004-06-15

English

Subject field(s)
  • Biochemistry
DEF

Major class of enzymes that catalyzes intramolecular re-arrangements or isomerization reactions. The class includes enzymes variously known as racemase, epimerase, and mutase.

French

Domaine(s)
  • Biochimie
DEF

Classe d'enzyme catalysant la transformation d'un corps en son isomère. Elle comprend : - les racémases qui catalysent la transformation d'un acide aminé L en acide aminé D, - les épimérases qui provoquent des interconventions d'oses : galactose->glucose, - les mutases catalysant le transfert d'un radical d'une partie d'une partie d'une molécule à une autre : méthylmalonlyl CoA -> succinyl CoA.

Spanish

Campo(s) temático(s)
  • Bioquímica
DEF
