Function

function

APS kinase catalyzes the synthesis of activated sulfate.
Catalyzes the synthesis of activated sulfate.
Proposed to provide activated sulfate for transfer to Nod factor. ATP sulfurylase may be the GTPase, regulating ATP sulfurylase activity.
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.

Caution

The sequence shown here is derived from an EMBL/GenBank/DDBJ whole genome shotgun (WGS) entry which is preliminary data.
