Function
function
APS kinase catalyzes the synthesis of activated sulfate.
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.
