An Entity of Type: enzyme, from Named Graph: http://dbpedia.org, within Data Space: dbpedia.org

In enzymology, a NAD+ glycohydrolase (EC 3.2.2.5) is an enzyme that catalyzes the chemical reaction NAD+ + H2O ADP-ribose + nicotinamide Thus, the two substrates of this enzyme are NAD+ and H2O, whereas its two products are ADP-ribose and nicotinamide. Unlike ADP-ribosyl cyclase/cyclic ADP-ribose hydrolase (EC 3.2.2.6), which catalyzes the same reaction, this reaction does not proceed through a cyclic ADP-ribose.

  • La NAD+ glycohydrolase est une glycoside hydrolase qui catalyse la réaction : NAD+ + H2O ADP-D-ribose + nicotinamide. Cette enzyme catalyse l'hydrolyse du NAD+ sans former d'ADP-ribose cyclique, ce qui la distingue de l'ADP-ribosyle cyclase. La NAD+ glycohydrolase de Streptococcus pyogenes (streptocoque A) intervient dans la pathogenèse de maladies telles que la fasciite nécrosante (syndrome du choc toxique streptococcique). L'enzyme du venin de Deinagkistrodon acutus (vipère des cent pas) porte également une activité enzymatique apyrase (EC 3.6.1.5). Cette enzyme porte plusieurs noms d'usage, souvent ambigus, tels que NADase (ambigu), NAD hydrolase (ambigu), NAD nucléosidase (ambigu) et NGA (nom d'un gène). (fr)
  • In enzymology, a NAD+ glycohydrolase (EC 3.2.2.5) is an enzyme that catalyzes the chemical reaction NAD+ + H2O ADP-ribose + nicotinamide Thus, the two substrates of this enzyme are NAD+ and H2O, whereas its two products are ADP-ribose and nicotinamide. Unlike ADP-ribosyl cyclase/cyclic ADP-ribose hydrolase (EC 3.2.2.6), which catalyzes the same reaction, this reaction does not proceed through a cyclic ADP-ribose. This enzyme belongs to the family of hydrolases, specifically those glycosylases that hydrolyse N-glycosyl compounds. The systematic name of this enzyme class is NAD+ glycohydrolase. Other names in common use include NAD+ nucleosidase, NADase, DPNase, DPN hydrolase, NAD hydrolase, diphosphopyridine nucleosidase, nicotinamide adenine dinucleotide nucleosidase, NAD glycohydrolase, NAD nucleosidase, and nicotinamide adenine dinucleotide glycohydrolase. This enzyme participates in nicotinate and nicotinamide metabolism and calcium signaling pathway. Calcium metabolism involves the regulation of the levels of calcium in the body. The role this calcium plays also includes providing enough calcium for bone mineralization. It serves as the basis for the structure and rigidity of bones. Calcium metabolism can lead to a variety of diseases which can involve renal function. High concentrations of calcium can lead to cell death or apoptosis. (en)
  • NAD+ヌクレオシダーゼ(NAD+ nucleosidase、EC 3.2.2.5)は、以下の化学反応を触媒する酵素である。 NAD+ + 水ADPリボース + ニコチンアミド 従って、この酵素は、NAD+と水の2つの基質、ADPリボースとニコチンアミドの2つの生成物を持つ。 この酵素は加水分解酵素、特にN-グリコシル化合物を分解するグリコシダーゼに分類される。系統名はNAD+グリコヒドロラーゼ(NAD+ glycohydrolase)である。NADアーゼ、DPNアーゼ、ジホスホピリジンヌクレオシダーゼ、ニコチンアミドアデニンジヌクレオチドヌクレオシダーゼ等と呼ばれることもある。ニコチン酸やニコチンアミドの代謝、またカルシウムシグナリング経路に関与している。 (ja)
