CC         Evidence={ECO:0000250|UniProtKB:A6QDA0};
CC   -!- COFACTOR:
CC       Name=pyridoxal 5'-phosphate; Xref=ChEBI:CHEBI:597326;
CC         Evidence={ECO:0000250|UniProtKB:A6QDA0};
CC   -!- PATHWAY: Siderophore biosynthesis. {ECO:0000250|UniProtKB:A6QDA0}.
CC   -!- SUBUNIT: Homodimer. {ECO:0000250|UniProtKB:A6QDA0}.
CC   -!- SIMILARITY: Belongs to the cysteine synthase/cystathionine beta-
CC       synthase family. SbnA subfamily. {ECO:0000305}.
