Abstract
The purpose of the present invention is to provide an organism having an ergothioneine productivity that is capable of easily producing ergothioneine within a short period of time at a high yield, as compared with a conventional technology, and, therefore, enables ergothioneine production on an industrial scale. This purpose can be achieved by a transformed fungus into which a gene encoding enzyme (1) or genes encoding enzymes (1) and (2) have been inserted and in which the inserted gene(s) are overexpressed. (1) an enzyme catalyzing a reaction of synthesizing hercynyl cysteine sulfoxide from histidine and cysteine in the presence of S-adenosyl methionine, iron (II) and oxygen. (2) An enzyme catalyzing a reaction of synthesizing ergothioneine from hercynyl cysteine sulfoxide using pyridoxal 5'-phosphate as a coenzyme.
