CC -!- FUNCTION: Catalyzes the reduction of a 3''-keto intermediate during the
CC biosynthesis of 2'-deoxymugineic acid (DMA) from L-Met. Involved in the
CC formation of phytosiderophores (MAs) belonging to the mugineic acid
CC family and required to acquire iron. {ECO:0000250|UniProtKB:W5DYE3}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=2'-deoxymugineate + NAD(+) = 3''-deamino-3''-oxonicotianamine
CC + H(+) + NADH; Xref=Rhea:RHEA:16141, ChEBI:CHEBI:15378,

CC -!- CATALYTIC ACTIVITY:
CC Reaction=2'-deoxymugineate + NADP(+) = 3''-deamino-3''-oxonicotianamine
CC + H(+) + NADPH; Xref=Rhea:RHEA:16137, ChEBI:CHEBI:15378,
CC ChEBI:CHEBI:57783, ChEBI:CHEBI:58349, ChEBI:CHEBI:58487,
CC ChEBI:CHEBI:58685; EC=1.1.1.285;
CC Evidence={ECO:0000250|UniProtKB:W5DYE3};
CC -!- PATHWAY: Siderophore biosynthesis. {ECO:0000250|UniProtKB:W5DYE3}.
CC -!- TISSUE SPECIFICITY: Mostly expressed in root tissues, observed in
CC mesocotyl and embryonic roots, seedling roots, crown and seedling
CC leafes, mature bracts, anthers, pistil, caryopsis and embryos.
CC {ECO:0000269|PubMed:28475636}.
CC -!- SIMILARITY: Belongs to the aldo/keto reductase family. {ECO:0000305}.
