It is an intermediate in the synthesis of ergothioneine, a compound found in certain fungi and mycobacteria. It has a role as a fungal metabolite. It is an ammonium betaine, a dipeptide and a sulfoxide. It is functionally related to a L-cysteine and a L-histidine. It is a conjugate acid of a N(alpha)-(L-gamma-glutamyl)-hercynyl-L-cysteine sulfoxide(1-)."}]
