Abstract excerpt
ATP sulfurylase (ATP: sulfate adenylyl transferase, EC 2.7.7.4), the first enzyme of the sulfate assimilation pathway, is present in the chloroplast and cytosol of plants. In Arabidopsis thaliana cDNA cloning revealed the existence of three ATP sulfurylase isoforms (APS1, -2, and -3) all of which appear to be localized in plastids. In the present study the cytosolic isoform was sought by searching the expressed...
