CC Rule:MF_02034, ECO:0000256|PIRNR:PIRNR017901};
CC -!- PATHWAY: Amino-acid biosynthesis; ergothioneine biosynthesis.
CC {ECO:0000256|HAMAP-Rule:MF_02034}.
CC -!- SIMILARITY: Belongs to the glutamate--cysteine ligase type 2 family.
CC EgtA subfamily. {ECO:0000256|HAMAP-Rule:MF_02034,
CC ECO:0000256|PIRNR:PIRNR017901}.
CC -!- CAUTION: The sequence shown here is derived from an EMBL/GenBank/DDBJ
CC whole genome shotgun (WGS) entry which is preliminary data.
