  • Rotte, C.; Leustek, T.
    Differential subcellular localization and expression of ATP sulfurylase and 5'-adenylylsulfate reductase during ontogenesis of Arabidopsis leaves indicates that cytosolic and plastid forms of ATP sulfurylase may have specialized functions (2000), Plant Physiol., 124, 715-724.

2.7.7.4 ATP + sulfate Arabidopsis sp. catalyzes a reaction in the sulfate assimilation pathway. The chloroplast isoenzyme, representing the more abundant enzyme form, declines in parallel with APS reductase activity during aging of leaf. The cytosolic isoenzyme plays a specialized function that is probably unrelated to sulfate reduction. A plausible function could be in generating APS for sulfate reactions diphosphate + adenylylsulfate
