Native Microorganism L-?-glycerophosphate oxidase LAB GRADE

In enzymology, a glycerol-3-phosphate oxidase (EC 1.1.3.21) is an enzyme that catalyzes the chemical reaction: sn-glycerol 3-phosphate + O2 ↔ glycerone phosphate + H2O2. Thus, the two substrates of this enzyme are sn-glycerol 3-phosphate and O2, whereas its two products are glycerone phosphate and H2O2. This enzyme belongs to the family of oxidoreductases, specifically those acting on the CH-OH group of donor with oxygen as acceptor. This enzyme participates in glycerophospholipid metabolism. It employs one cofactor, FAD.http://www.creative-enzymes.com/product/Native-Microorganism-L-glycerophosphate-Oxidase_796.html

Native Pseudomonas sp. Oxaloacetate decarboxylase LAB GRADE

Oxaloacetate decarboxylase is a carboxy-lyase involved in the conversion of oxaloacetate into pyruvate. It is categorized under EC 4.1.1.3. In some bacteria this enzyme is a trimer, composed of alpha, beta and gamma subunits. The beta and gamma subunits are integral membrane proteins.http://www.creative-enzymes.com/product/Native-Pseudomonas-Sp-Oxaloacetate-Decarboxylase_757.html

Aspartate Aminotransferase from Human, recombinant LAB GRADE

Aspartate transaminase (AST), also called aspartate aminotransferase is commonly known as sgot (AspAT/ASAT/AAT) or serum glutamic oxaloacetic transaminase (SGOT), is a pyridoxal phosphate (PLP)-dependent transaminase enzyme (EC2.6.1.1). AST catalyzes the reversible transfer of an α-amino group between aspartate and glutamate and, as such, is an important enzyme in amino acid metabolism. AST is found in the liver, heart, skeletal muscle, kidneys, brain, and red blood cells, and it is commonly measured clinically as a marker for liver health.http://www.creative-enzymes.com/product/Aspartate-Aminotransferase-From-Human-Recombinant_724.html

Native Microorganism P-hydroxybenzoate hydroxylase LAB GRADE

In enzymology, a 4-hydroxybenzoate 3-monooxygenase (EC 1.14.13.2) is an enzyme that catalyzes the chemical reaction: 4-hydroxybenzoate + NADPH + H+ + O2 ↔ protocatechuate + NADP+ + H2O. The 4 substrates of this enzyme are 4-hydroxybenzoate, NADPH, H+, and O2, whereas its 3 products are protocatechuate, NADP+, and H2O. This enzyme belongs to the family of oxidoreductases, specifically those acting on paired donors, with O2 as oxidant and incorporation or reduction of oxygen. The oxygen incorporated need not be derived from O2 with NADH or NADPH as one donor, and incorporation of one atom o oxygen into the other donor. This enzyme participates in benzoate degradation via hydroxylation and 2,4-dichlorobenzoate degradation. It employs one cofactor, FAD.http://www.creative-enzymes.com/product/Native-Microorganism-Phydroxybenzoate-Hydroxylase_799.html

Native Bacillus sp. Purine Nucleoside Phosphorylase LAB GRADE

Purine nucleoside phosphorylase (also known as PNPase) is an enzyme (EC 2.4.2.1) involved in purine metabolism. PNP metabolizes adenosine into adenine, inosine into hypoxanthine, and guanosine into guanine, in each case creating ribose phosphate. NP encodes the enzyme purine nucleoside phosphorylase that together with adenosine deaminase (ADA) serves a key role in purine catabolism, referred to as the salvage pathway. Mutations in either enzyme result in a severe combined immunodeficiency (SCID). Confusingly, the same abbreviation (PNPase), is also used for another, otherwise unrelated, enzyme, namely Polynucleotide Phosphorylase.http://www.creative-enzymes.com/product/Native-Bacillus-Sp-Purine-Nucleoside-Phosphorylase_760.html

Native Bacillus subtilis L-Alanine Dehydrogenase LAB GRADE 97%

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.http://www.creative-enzymes.com/product/Native-Bacillus-Subtilis-LAlanine-Dehydrogenase_1246.html
