2.7.7.4 | ATP + sulfate |
the enzyme catalyzes the first step of sulfate metabolism |
2.7.7.4 | ATP + sulfate |
key enzyme of sulfate assimilation |
2.7.7.4 | ATP + sulfate |
enzyme plays a crucial role in sulfate activation |
2.7.7.4 | ATP + sulfate |
the enzyme catalyzes the first step of sulfate activation |
2.7.7.4 | ATP + sulfate |
the ATP sulfurylase-adenylylsulfate complex does not serve as a substrate for APS kinase, i.e. there is no substrate chanelling of APS between the two sulfate-activating enzymes |
2.7.7.4 | ATP + sulfate |
first enzyme of the two-step sulfate activation sequence |
2.7.7.4 | ATP + sulfate |
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 |
2.7.7.4 | ATP + sulfate |
regulation of ATP sulfurylase activity and SO42- uptake by S demand is related to GSH rather than to the GSH/GSSG ratio, and is distinct from the oxidative stress response |
