Function
function
APS kinase catalyzes the synthesis of activated sulfate.
With CysD forms the ATP sulfurylase (ATPS) that catalyzes the adenylation of sulfate producing adenosine 5'-phosphosulfate (APS) and diphosphate, the first enzymatic step in sulfur assimilation pathway. APS synthesis involves the formation of a high-energy phosphoric-sulfuric acid anhydride bond driven by GTP hydrolysis by CysN coupled to ATP hydrolysis by CysD.
Catalytic activity
- sulfate + ATP + H+ = adenosine 5'-phosphosulfate + diphosphate
Pathway
Sulfur metabolism; hydrogen sulfide biosynthesis; sulfite from sulfate: step 1/3.
