Abstract
The purpose of the present invention is to provide a method for producing selenoneine that allows production of selenoneine at higher yields, even if an inorganic selenium compound is used as a selenium compound. This purpose can be achieved by a method for producing selenoneine, comprising the step of applying histidine and a selenium compound to a transformant to obtain selenoneine, wherein the transformant has at least one gene selected from the group consisting of a SatA gene, a CysB gene and a MetR gene, and an EgtA gene inserted therein and can overexpress the inserted genes.

A method for producing selenoneine, comprising the step of applying histidine and a selenium compound to a transformant to obtain selenoneine, wherein the transformant has at least one gene selected from the group consisting of a SatA gene, a CysB gene and a MetR gene, and an EgtA gene inserted therein and can overexpress the inserted genes, and
- wherein the transformant is a microorganism of the genus Aspergillus selected from the group consisting of Aspergillus sojae, Aspergillus oryzae, Aspergillus niger, Aspergillus tamarii, Aspergillus luchuensis, Aspergillus usamii, Aspergillus aculeatus and Aspergillus saitoi.
A transformant that has at least one gene selected from the group consisting of a SatA gene, a CysB gene and a MetR gene, and an EgtA gene inserted therein and can overexpress the inserted genes,
- wherein the transformant is a microorganism of the genus Aspergillus selected from the group consisting of Aspergillus sojae, Aspergillus oryzae, Aspergillus niger, Aspergillus tamarii, Aspergillus luchuensis, Aspergillus usamii, Aspergillus aculeatus and Aspergillus saitoi.
