ROUP [4 records]

Record 1 2011-01-05

English

Subject field(s)
  • Biological Sciences
DEF

Class of enzymes in which a covalent thioester bond is formed between an acyl roup of the substrate and the sulfhydryl group of a specific cysteine residue in the active site of the enzyme. These include glyceraldehyde-phosphate dehydrogenase and the proteolytic enzyme papain.

French

Domaine(s)
  • Sciences biologiques
DEF

Classe d'enzymes dans laquelle il y a formation d'une liaison thioester covalente entre un groupement acyle du substrat et le groupement sulfhydryle d'un résidu cystéine spécifique au site actif de l'enzyme.

Record 2 2004-01-20

English

Subject field(s)
  • Biochemistry
  • Genetics
DEF

One of the organic bases found as a side roup in DNA.

OBS

Adenine always pairs with thymine and guanine with cytosine, but the sequence of the bases along a strand of DNA is variable and carries a particular coded message.

French

Domaine(s)
  • Biochimie
  • Génétique
DEF

Substance basique dérivée de la pyrimidine et entrant dans la constitution dés acides désoxyribonucléiques de la cellule vivante.

OBS

L'appariement des bases se fait toujours entre l'adénine et la thymine de même qu'entre la guanine et la cytosine. Apparemment, la succession des bases sur un brin de DNA est tout à fait variable, mais leur arrangement constitue en fait un message codé particulier.

Record 3 1997-07-09

English

Subject field(s)
  • Chemical Engineering
DEF

The ratio of the rate constants of two reactions that differ only in the identity of the element of the atom in the leaving group by which the leaving roup is attached to the rest of the substrate molecule. As for isotope effects, a ratio of unity is thought of as a null effect.

French

Domaine(s)
  • Génie chimique
DEF

Rapport des constantes de vitesse de deux réactions qui ne diffèrent que par l'identité de l'atome du groupe partant par lequel ce groupe est lié au reste de la molécule que l'on considère comme substrat. Comme dans le cas des effets isotopiques, on considère que l'effet est nul quand ce rapport est égal à un.
