Function

function

Catalyzes the first intracellular reaction of sulfate assimilation, forming adenosine-5'-phosphosulfate (APS) from inorganic sulfate and ATP. Plays an important role in sulfate activation as a component of the biosynthesis pathway of sulfur-containing amino acids.

Caution

Lacks conserved residue(s) required for the propagation of feature annotation.
The sequence shown here is derived from an EMBL/GenBank/DDBJ whole genome shotgun (WGS) entry which is preliminary data.

Catalytic activity

Activity regulation

Allosterically inhibited by 3'-phosphoadenosine 5'-phosphosulfate (PAPS).

Pathway

Sulfur metabolism; hydrogen sulfide biosynthesis; sulfite from sulfate: step 1/3.

Features

Showing features for region, domain.

Type
IDPosition(s)Description
Region1-169N-terminal
Domain4-165ATP-sulfurylase PUA-like
Domain174-387Sulphate adenylyltransferase catalytic
Region395-573Allosteric regulation domain; adenylyl-sulfate kinase-like

Domain

The adenylyl-sulfate kinase (APS kinase) is non-functional. It is involved in allosteric regulation by PAPS. PAPS binding induces a large rotational rearrangement of domains lowering the substrate affinity of the enzyme.

Sequence similarities

In the C-terminal section; belongs to the APS kinase family.
In the N-terminal section; belongs to the sulfate adenylyltransferase family.
