| Alanine Dehydrogenase from Bacillus cereus, Recombinant | L-Alanine dehydrogenase is an A-stereospecific dehydrogenase that catalyzes the reversible deamination of L-alanine to pyruvate and ammonium. It is important for the geneRation of pyruvate during sporulation. L-Alanine dehydrogenase from Bacillus subtilis has a predominately ordered kinetic mechanism in which NAD binds before L-alanine. Subsequently, ammonia, pyruvate, and NADH are released in that specific order. Optimal pH for the amination reaction is 8.8-9.0, whereas it is 10-10.5 for the deamination reaction. The enzyme is inactivated by divalent metal ions and p-chloromercuribenzoate, mercuric ion being most effective. The inactivation may be reversed by L-or D-cysteine. Group: Enzymes. Synonyms: L-Alanine Dehydrogenase; Alanine dehydrogenase; EC 1.4.1.1; 9029-06-5; AlaDH; NAD+-linked alanine dehydrogenase; alpha-alanine dehydrogenase; NAD+-dependent alanine dehydrogenase; alanine oxidoreductase; NADH-dependent alan.

| Murexide | REAGENT (NH4C8H4N5O6, or C8H5N5O6·NH3), also called ammonium purpurate or MX, is the ammonium salt of purpuric acid. It may be prepared by heating alloxantin in ammonia gas to 100°C, or by boiling uramil (5-aminobarbituric acid) with mercury oxide. W.N. Hartley found considerable difficulty in obtaining specimens of REAGENT sufficiently pure to give concordant results when examined by means of their absorption spectra, and consequently devised a new method of preparation for REAGENT. In this process alloxantin is dissolved in a large excess of boiling absolute alcohol, and dry ammonia gas is passed into the solution for about three hours. The solution is then filtered from the precipitated REAGENT, which is washed with absolute alcohol and dried. The salt obtained in this way is in the anhydrous state. It may also be prepared by digesting alloxan with alcoholic ammonia at about 78°C; the purple solid so formed is easily soluble in water, and the solution produced is indistinguishable from one of REAGENT.REAGENT in its dry state has the appearance of a reddish purple powder, slightly soluble in water. In solution, its color ranges from yellow in strong acidic pH through reddish-purple in weakly acidic solutions to blue-purple in alkaline solutions. The pH for titration of calcium is 11.3.Justus von Liebig and Friedrich Wöhler in Giessen, Germany, had investigated the purple product, REAGENT, obtained from snake excrement in the 1 |  |

| Native Clostridium perfringens (C. welchII) Choloylglycine Hydrolase | Choloylglycine hydrolase (EC 3.5.1.24) is an N-terminal nucleophilic (Ntn) hydrolase that catalyzes the hydrolysis of amide bonds, libeRates the glycine/taurine moiety from the steroid core and eventually yields unconjugated bile acids. Agents that oxidize thiol groups (e.g., p-mercuribenzoate, iodoacetamide, Hg2+, Cu2+, and Cd2+) have been shown to strongly inhibit bile salt hydrolase (BSH) activity in Clostridium perfringens. Applications: The enzyme from creative enzymes has been used in the analysis of bile samples in various studies. Group: Enzymes.

| Native Coriolus versicolor Laccase | Laccases are copper-containing oxidase enzymes that are found in many plants, fungi, and microorganisms. The copper is bound in several sites; Type 1, Type 2, and/or Type 3. The ensemble of types 2 and 3 copper is called a trinuclear cluster. Type 1 copper is available to action of solvents, such as water. It can be displaced by mercury, substituted by cobalt or removed via a copper complexone. Removal of type 1 copper causes a decrease in laccase activity. Cyanide can remove all copper from the enzyme however re-embedding with type 1 and type 2 copper has been shown to be impossible. Type 3 copper however can be embed back into the enzyme. Laccases act on phenols and simila...ganisms. the copper is bound in several sites; type 1, type 2, and/or type 3. the ensemble of types 2 and 3 copper is called a trinuclear cluster. type 1 copper is available to action of solvents, such as water. it can be displaced by mercury, substituted by cobalt or removed via a copper complexone. removal of type 1 copper causes a decrease in laccase activity. cyanide can remove all copper from the enzyme however re-embedding with type 1 and type 2 copper has been shown to be impossible. type 3 copper however can be embed back into the enzyme. laccases act on phenols and similar molecules, performing a one-electron oxidations, which remain poorly defined. it is proposed t | |
