The present invention relates to novel monooxygenase nucleic acids and polypeptides created using mutagenesis, DNA shuffling, or both, in a single iteration or multiple iterations, and methods for their creation and use. The monooxygenase enzymes of the present disclosure have particular utility as biocatalysts in industrial chemical redox reactions, such as the oxidation of aromatic hydrocarbons, for example, toluene, benzene, or nitrobenzene, into industrially desirable products. The systems and processes of the present invention are especially useful for the coupled synthesis and recovery of catechols, methylcatechols, resorcinols, methylresorcinols, hydroquinones, methylhydroquinones, hydroxybenzenes, cresols, nitrobenzenes, and nitrohydroxyquinones.
本发明涉及使用突变、DNA重组或两者结合的方法,在单次迭代或多次迭代中创建的新型单加氧酶核酸和多肽,以及它们的创建和使用方法。本公开的单加氧酶酶在工业化学氧化还原反应中具有特定的生物催化剂实用性,例如将芳香族烃类(例如甲苯、苯或硝基苯)氧化成工业上所需的产品。本发明的系统和过程特别适用于咖啡酚、甲基咖啡酚、间苯二酚、甲基间苯二酚、对苯二酚、甲基对苯二酚、羟基苯、甲酚、硝基苯和硝基羟基苯的耦合合成和回收。
