>cd02993 PDI_a_APS_reductase PDIa family, 5'-Adenylylsulfate (APS) reductase subfamily; composed of plant-type APS reductases containing a C-terminal redox active TRX domain and an N-terminal reductase domain which is part of a superfamily that includes N type ATP PPases. APS reductase catalyzes the reduction of activated sulfate to sulfite, a key step in the biosynthesis of sulfur-containing metabolites. Sulfate is first activated by ATP sulfurylase, forming APS, which can be phosphorylated to 3'-phosphoadenosine-5'-phosphosulfate (PAPS). Depending on the organism, either APS or PAPS can be used for sulfate reduction. Prokaryotes and fungi use PAPS, whereas plants use both APS and PAPS. Since plant-type APS reductase uses glutathione (GSH) as its electron donor, the C-terminal domain may function like glutaredoxin, a GSH-dependent member of the TRX superfamily. The flow of reducing equivalents goes from GSH - C-terminal TRX domain - N-terminal reductase domain - APS. Plant-type APS red
