sulfate adenylyltransferase

(redirected from ATP sulfurylase)

sul·fate aden·y·lyl·trans·fer·ase

an enzyme that catalyzes a step in the pathway for the synthesis of active sulfate; the enzyme reacts ATP with sulfate to produce pyrophosphate and adenosine 5'-phosphosulfate (APS).
Synonym(s): ATP sulfurylase

Selenium also promoted expression levels of ATP sulfurylase of the tomato varieties.
thaliana overexpressing APR (APS reductase) and ATP sulfurylase played significant roles in a greater selenate reduction of total Se, however the overexpressing in SAT (serine acetyl transferase) led to a tiny reduction in organic selenium.
Expression levels of ATP sulfurylase (APS) of variety KT30 first decreased and then increased and reached maximum at 10 mg*kg-1 Se treatment; it was 3.
It was reported that the ATP sulfurylase activity was highest in seeds harvested 15 d after the R5 stage (about 1600 nmol ATP g fresh [wt.

The activity of ATP sulfurylase is Known to increase in response to S deficiency (Zink, 1984; Archer, 1987; Lappartient and Touraine, 1996).
Consistent with its occurring in chloroplasts (as noted above) activity of ATP sulfurylase during vegetative growth of soybean has been observed to be largely confined to leaf tissue (Adams and Rinne, 1969).
As part of a broader effort to improve soybean protein quality, the objective of this study was to characterize the location and duration of activity of ATP sulfurylase on a whole-plant level, comparing activity in leaf, stem, pod wall, and seed tissue during seed filling in soybean.
