摘要:
The present invention provides genes that encode the N-acetyl-(R,S)-β-amino acid acylases. The N-acetyl-(R,S)-β-amino acid acylases were isolated and purified from bacterial cells and the nucleotide sequences were determined. A host, such as Escherichia coli, was used to construct a high-expression system for these genes. The N-acetyl-(R)-β-amino acid acylase produced by Burkholderia sp. AJ110349 (FERM BP-10366) includes, for example, the protein having the amino acid sequence shown in SEQ. ID. NO. 8. The gene encoding this enzyme includes, for example, the DNA having the nucleotide sequence as shown in SEQ. ID. NO. 7. The N-acetyl-(S)-β-amino acid acylase produced by Burkholderia sp. AJ110349 (FERM BP-10366) includes, for example, the protein having the amino acid sequence shown in SEQ. ID. NO. 10. The gene encoding this enzyme includes, for example, the DNA having the nucleotide sequence shown inshown in SEQ. ID. NO. 9. The N-acetyl-(R)-β-amino acid acylase produced by Variovorax sp. AJ110348 (FERM BP-10367) includes, for example, the protein comprised of the amino acid sequence shown in SEQ. ID. NO. 12. The gene encoding this enzyme includes, for example, the DNA having the nucleotide sequence shown inshown in SEQ. ID. NO. 11.

摘要:
It is an object of the present invention to provide a procedure for realizing inexpensive and simple production of 3-indole-pyruvic acid. A transformant is made using a polynucleotide having a specific nucleotide sequence encoding a protein having an oxidase activity, and oxidase is generated by culturing the transformant in a medium to accumulate the oxidase in the medium and/or the transformant. Further, tryptophan is converted into 3-indole-pyruvic acid in the presence of the transformant and/or a culture thereof to produce 3-indole-pyruvic acid.

摘要:
The present invention provides a method for producing L-fuculose and L-fucose which is suitable as an industrial method. L-Fuculose is synthesized from L-fucitol in the presence of a microorganism-derived protein having a dehydrogenase activity which results in production of L-fuculose from L-fucitol. The reaction system preferably contains NADH oxidase. L-Fuculose thus synthesized is then converted into L-fucose.
