Comments
[?]
| FUNCTION | Catalyzes the oxidative sulfurization of hercynine (N- alpha,N-alpha,N-alpha-trimethyl-L-histidine) into hercynyl-gamma-L- glutamyl-L-cysteine sulfoxide, a step in the biosynthesis pathway of ergothioneine. |
| CATALYTIC ACTIVITY | Reaction=gamma-L-glutamyl-L-cysteine + hercynine + O2 = gamma-L- glutamyl-hercynylcysteine S-oxide + H2O; Xref=Rhea:RHEA:42672, ChEBI:CHEBI:15377, ChEBI:CHEBI:15379, ChEBI:CHEBI:15781, ChEBI:CHEBI:58173, ChEBI:CHEBI:82703; EC=1.14.99.50; |
| COFACTOR | Name=Fe(2+); Xref=ChEBI:CHEBI:29033; |
| PATHWAY | Amino-acid biosynthesis; ergothioneine biosynthesis. |
| SIMILARITY | Belongs to the EgtB family. |
