Patent ID: 8518665

Claim:
A method for producing 3-indole-pyruvic acid, comprising converting tryptophan into 3-indole-pyruvic acid in the presence of an isolated recombinant host cell and/or a culture thereof, wherein the recombinant host cell comprises a recombinant polynucleotide comprising a polynucleotide selected from the group consisting of the following (a) to (d): (a) a polynucleotide encoding a protein comprising the amino acid sequence of SEQ ID NO:2; (b) a polynucleotide encoding a protein which consists of an amino acid sequence comprising a substitution, deletion and/or insertion of one to ten amino acids in the amino acid sequence of SEQ ID NO:2 and has an L-Trp deaminase activity; (c) a polynucleotide encoding a protein which consists of an amino acid sequence having 95% or more homology to the amino acid sequence of SEQ ID NO:2 and has an L-Trp deaminase activity; and (d) a polynucleotide comprising the nucleotide sequence of nucleotide positions 61 to 1476 in the nucleotide sequence of SEQ ID NO:1.
