Figure 1 Biosynthetic pathway of mugineic acid family phytosiderophores. Three molecules of S-adenosyl methionine are combined by NA synthase (NAS) to form nicotianamine (NA). The amino group of NA is transferred by NA aminotransferase (NAAT), and the resultant 3″-keto intermediate is reduced to 2′-deoxymugineic acid (DMA) by deoxymugineic acid synthase (DMAS). The subsequent steps differ with the plant species and cultivar.
Figure 2 Phylogenetic characterization of DMAS genes. Unrooted phylo-genetic tree of the aldo-keto reductase superfamily (AKR4). The details and accession numbers of the AKR proteins are at www.med.upenn.edu/akr/members.html. AK102609 is a homolog of OsDMAS1 that lacks DMAS activity.
