unspecific monooxygenase
A group of P-450 heme-thiolate proteins, acting on a wide range of substrates including many xenobiotics, steroids, fatty acids, vitamins and prostaglandins; reactions catalysed include hydroxylation, epoxidation, N-oxidation, sulfooxidation, N-, S- and O-dealkylations, desulfation, deamination, and reduction of azo, nitro and N-oxide groups. Together with EC 1.6.2.4, NADPH-hemoprotein reductase, it forms a system in which two reducing equivalents are supplied by NADPH. Some of the reactions attributed to EC 1.14.15.3, alkane 1-monooxygenase, belong here. Group: Enzymes. Synonyms: microsomal monooxygenase; xenobiotic monooxygenase; aryl-4-monooxygenase; aryl hydrocarbon hydroxylase; microsomal P-450; flavoprotein-linked monooxygenase; flavoprotein monooxygenase; substrate,reduced-flavoprotein:oxygen oxidoreductase (RH-hy. Enzyme Commission Number: EC 1.14.14.1. CAS No. 9038-14-6. Storage: Store it at +4 ?C for short term. For long term storage, store it at -20 ?C?-80 ?C. Form: Liquid or lyophilized powder. EXWM-0906; unspecific monooxygenase; EC 1.14.14.1; 9038-14-6; microsomal monooxygenase; xenobiotic monooxygenase; aryl-4-monooxygenase; aryl hydrocarbon hydroxylase; microsomal P-450; flavoprotein-linked monooxygenase; flavoprotein monooxygenase; substrate,reduced-flavoprotein:oxygen oxidoreductase (RH-hydroxylating or -epoxidizing). Cat No: EXWM-0906.
versatile peroxidase
A hemoprotein. This ligninolytic peroxidase combines the substrate-specificity characteristics of the two other ligninolytic peroxidases, EC 1.11.1.13, manganese peroxidase and EC 1.11.1.14, lignin peroxidase. Unlike these two enzymes, it is also able to oxidize phenols, hydroquinones and both low- and high-redox-potential dyes, due to a hybrid molecular architecture that involves multiple binding sites for substrates. Group: Enzymes. Synonyms: VP; hybrid peroxidase; polyvalent peroxidase; reactive-black-5:hydrogen-peroxide oxidoreductase. Enzyme Commission Number: EC 1.11.1.16. CAS No. 42613-30-9, 114995-15-2. Versatile Peroxidase. Storage: Store it at +4 ?C for short term. For long term storage, store it at -20 ?C?-80 ?C. Form: Liquid or lyophilized powder. EXWM-0497; versatile peroxidase; EC 1.11.1.16; 42613-30-9, 114995-15-2; VP; hybrid peroxidase; polyvalent peroxidase; reactive-black-5:hydrogen-peroxide oxidoreductase. Cat No: EXWM-0497.
vitamin D 25-hydroxylase
A microsomal enzyme isolated from human and mouse liver that bioactivates vitamin D3. While multiple isoforms (CYP27A1, CYP2J2/3, CYP3A4, CYP2D25 and CYP2C11) are able to catalyse the reaction in vitro, only CYP2R1 is thought to catalyse the reaction in humans in vivo. The direct electron donor to the enzyme is EC 1.6.2.4, NADPH-hemoprotein reductase. Group: Enzymes. Synonyms: vitamin D2 25-hydroxylase; vitamin D3 25-hydroxylase; CYP2R1. Enzyme Commission Number: EC 1.14.14.24. Storage: Store it at +4 ?C for short term. For long term storage, store it at -20 ?C?-80 ?C. Form: Liquid or lyophilized powder. EXWM-0921; vitamin D 25-hydroxylase; EC 1.14.14.24; vitamin D2 25-hydroxylase; vitamin D3 25-hydroxylase; CYP2R1. Cat No: EXWM-0921.
