RT producer of the benzoxazol antibiotic caboxamycin.";
RL Submitted (APR-2014) to the EMBL/GenBank/DDBJ databases.
CC -!- FUNCTION: Catalyzes the oxidative sulfurization of hercynine (N-
CC alpha,N-alpha,N-alpha-trimethyl-L-histidine) into hercynyl-gamma-L-
CC glutamyl-L-cysteine sulfoxide, a step in the biosynthesis pathway of
CC ergothioneine. {ECO:0000256|HAMAP-Rule:MF_02035}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=gamma-L-glutamyl-L-cysteine + hercynine + O2 = gamma-L-
CC glutamyl-hercynylcysteine S-oxide + H2O; Xref=Rhea:RHEA:42672,
CC ChEBI:CHEBI:15377, ChEBI:CHEBI:15379, ChEBI:CHEBI:15781,
CC ChEBI:CHEBI:58173, ChEBI:CHEBI:82703; EC=1.14.99.50;
CC Evidence={ECO:0000256|HAMAP-Rule:MF_02035};
CC -!- COFACTOR:
CC Name=Fe(2+); Xref=ChEBI:CHEBI:29033;
CC Evidence={ECO:0000256|HAMAP-Rule:MF_02035};
CC -!- PATHWAY: Amino-acid biosynthesis; ergothioneine biosynthesis.
CC {ECO:0000256|ARBA:ARBA00037882, ECO:0000256|HAMAP-Rule:MF_02035}.
CC -!- SIMILARITY: Belongs to the EgtB family. {ECO:0000256|HAMAP-
CC Rule:MF_02035}.
CC -!- CAUTION: The sequence shown here is derived from an EMBL/GenBank/DDBJ
CC whole genome shotgun (WGS) entry which is preliminary data.
CC {ECO:0000313|EMBL:KDQ71118.1}.
