Abstract:
A method for a chemoselective and regioselective enzyme mediated oxidation of carbon-hydrogen bonds of substrates using a Geobacillus kaustophilus 'Old Yellow Enzyme' is provided. It is shown that OYEs can be used to facilitate the bioxidation of substrates, such as testosterone. It is also shown that the use of OYEs allows for the production of oxidized substrates in one step reactions, which are otherwise not accessible or only accessible after complex and inefficient multi-step reactions. In addition, the OYE used shows high stability at high temperature. An exemplary embodiment is provided showing the use of an OYE to convert testosterone to 6α- hydroxytestosterone.
Abstract:
Nucleic acids encoding cytochrome P450 variants are provided. The cytochrome P450 variants of have a higher alkane-oxidation capability, alkene-oxidation capability, and/or a higher organic-solvent resistance than the corresponding wild-type or parent cytochrome P450 enzyme. A preferred wild-type cytochrome P450 is cytochrome P450 BM-3. Preferred cytochrome P450 variants include those having an improved capability to hydroxylate alkanes and epoxidate alkenes comprising less than 8 carbons, and have amino acid substitutions corresponding to V78A, H236Q, and E252G of cytochrome P450 BM-3. Preferred cytochrome P450 variants also include those having an improved hydroxylation activity in solutions comprising co-solvents such as DMSO and THF, and have amino acid substitutions corresponding to T235A, R471A, E494K, and S1024E of cytochrome P450 BM-3.
Abstract:
A method of selective biooxidation to non activated carbon-hydrogen bonds of substances using a Geobacillus kaustophilus 'Old Yellow Enzyme1 is provided". It is shown that OYEs can be used to facilitate the biooxydation of substances, such as testosterone. It is also shown that OYE can introduce double bonds to form alpha, betaalpha, beta desaturated ketones. Furthermore, it is also shown that the use of OYEs allows for the production of oxidized substances in one step reactions, which are otherwise not accessible or only accessible after complex and inefficient multi-step reactions. In addition, the OYE used shows high stability (e.g. at high temperature, or in long lasting bioconversions). An exemplary embodiment is provided showing the use of an OYE to convert testosterone to 6α- hydroxytestosterone.
Abstract:
A new process for enhancing the hydrophilicity of the surface of a polyolefin or polyolefin copolymer article is characterized in that the surface is treated with an enzyme selected from oxidoreductases, especially of the cytochrome P450 family or enzymes classified as EC 1.13 or EC 1.14. The process is especially useful for the treatment of polypropylene films, fibres, or fabrics, inter alia for use in sanitary articles, threads, yarns, fabrics, textiles, garments, technical or household articles, printed or dyed cover films or packaging films.
