Abstract
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.
