De Johannes Hendrik Winde

The invention includes a process of producing methyl methacrylate or derivatives thereof is described. The process includes the steps of converting 2-butanone to methyl propionate using a Baeyer-Villiger monooxygenase, and treating the methyl propionate produced to obtain methyl methacrylate or derivatives thereof. A method of preparing polymers or copolymers of methyl methacrylate or its derivatives is also described.

Process for the production of methyl methacrylate

The invention relates to a polypeptide having oxidoreductase activity which comprises the amino acid sequence set out in SEQ ID NO: 3 or an amino acid sequence encoded by the nucleotide sequence of SEQ ID NO: 4, or a variant polypeptide thereof having 45% or more sequence identity with the sequence of SEQ ID NO: 3. The invention also relates to a process for the production of 2,5-furan-dicarboxylic acid (FDCA) or production of 5-hydroxymethyl-2-furancarboxylic acid (HMF acid).
