| cobyrinate a,c-diamide synthase | This enzyme is the first glutamine amidotransferase that participates in the anaerobic (early cobalt insertion) biosynthetic pathway of adenosylcobalamin, and catalyses the ATP-dependent synthesis of cobyrinate a,c-diamide from cobyrinate using either L-glutamine or ammonia as the nitrogen source.

| L-Glutamate Dehydrogenase (Crude Enzyme) | Glutamate dehydrogenase (GLDH) is an enzyme, present in most microbes and the mitochondria of eukaryotes, as are some of the other enzymes required for urea synthesis, that converts glutamate to α-ketoglutarate, and vice versa.

| 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 Bacillus subtilis L-Alanine Dehydrogenase | 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-...genase.

| Native Bovine L-Glutamic Dehydrogenase | L-glutamic dehydrogenase catalyzes the conversion of glutamate to α-ketoglutarate. Mammalian forms of this enzyme, including this bovine form, can use either NADP (H) or NAD (H) as coenzymes. L-glutamic dehydrogenase plays a unique role in mammalian metabolism.

| Nitrilase (Crude Enzyme) | Nitrilase enzymes catalyse the hydrolysis of nitriles to carboxylic acids and ammonia, without the formation of "free" amide intermediates. Nitrilases are involved in natural product biosynthesis and post translational modifications in plants, animals, fungi and certain prokaryotes. Nitrilases can also be used as catalysts in preparative organic chemistry. Among others, nitrilases have been used for the resolution of racemic mixtures. Nitrilase should not be confused with nitrile hydratase (nitrile hydro-lyase; EC 4. 2. 1. 84) which hydrolyses nitriles to amides. Nitrile hydratases are almost invariably co-expressed with an amidase, which converts the amide to the carboxylic acid, consequently it can sometimes be difficult to distinguish nitrilase activity from nitrile hydratase plus amidase activity. This product with the indicated enzyme activity was briefly purified from engineered E. coli. Applications: Synthesis; industry. Group: Enzymes. Synonyms: acetonitrilase; benzonitrilase. Enzyme Commission Number: EC 3.5.5.1. CAS No. 9024-90-2. Nitrilase. Activity: Undetermined. Appearance: Clear to translucent yellow solution. Storage: at -20 °C or lower, for at least 1 month.

| Threonine Deaminase (Crude Enzyme) | Threonine ammonia-lyase, also commonly referred to as threonine deaminase or threonine dehydratase, is an enzyme responsible for catalyzing the conversion of L-threonine into alpha-ketobutyrate and ammonia. Alpha-ketobutyrate can be converted into L-isoleucine, so threonine ammonia-lyase functions as a key enzyme in BCAA synthesis. It employs a pyridoxal-5-phosphate cofactor, similar to many enzymes involved in amino acid metabolism.
