2.7.7.4 sulfate adenylyltransferaseIUBMB Comments
The human phosphoadenosine-phosphosulfate synthase (PAPS) system is a bifunctional enzyme (fusion product of two catalytic activities). In a first step, sulfate adenylyltransferase catalyses the formation of adenosine 5'-phosphosulfate (APS) from ATP and inorganic sulfate. The second step is catalysed by the adenylylsulfate kinase portion of 3'-phosphoadenosine 5'-phosphosulfate (PAPS) synthase, which involves the formation of PAPS from enzyme-bound APS and ATP. In contrast, in bacteria, yeast, fungi and plants, the formation of PAPS is carried out by two individual polypeptides, sulfate adenylyltransferase (EC 2.7.7.4) and adenylyl-sulfate kinase (EC 2.7.1.25).

adenylylsulfate transgenics are more tolerant than wild-type to As(III), As(V), Cd2+, Cu2+, Hg2+, and Zn2+, but less tolerant to Mo6+ and V6+. The APS seedlings has up to 2.5-fold higher shoot concentrations of As(III), As(V), Hg2+, Mo6+, Pb2+, and V6+, and somewhat lower Cr3+ levels. Mature APS plants contained up to 2.5fold higher shoot concentrations of Cd2+, Cr3+, Cu2+, Mo6+, V6+, and W than wild type. They also contain 1.5fold to 2fold higher levels of the essential elements Fe, Mo, and S in most of the treatments

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

adenylylsulfate transgenics are more tolerant than wild-type to As(III), As(V), Cd2+, Cu2+, Hg2+, and Zn2+, but less tolerant to Mo6+ and V6+. The APS seedlings has up to 2.5-fold higher shoot concentrations of As(III), As(V), Hg2+, Mo6+, Pb2+, and V6+, and somewhat lower Cr3+ levels. Mature APS plants contained up to 2.5fold higher shoot concentrations of Cd2+, Cr3+, Cu2+, Mo6+, V6+, and W than wild type. They also contain 1.5fold to 2fold higher levels of the essential elements Fe, Mo, and S in most of the treatments
