Protein

Bifunctional 3'-phosphoadenosine 5'-phosphosulfate synthase 2

Gene

Papss2

Organism
Mus musculus (Mouse)
Status
Reviewed-Annotation score: -Experimental evidence at protein leveli

Functioni

Bifunctional enzyme with both ATP sulfurylase and APS kinase activity, which mediates two steps in the sulfate activation pathway. The first step is the transfer of a sulfate group to ATP to yield adenosine 5'-phosphosulfate (APS), and the second step is the transfer of a phosphate group from ATP to APS yielding 3'-phosphoadenylylsulfate (PAPS: activated sulfate donor used by sulfotransferase). In mammals, PAPS is the sole source of sulfate; APS appears to be only an intermediate in the sulfate-activation pathway. May have a important role in skeletogenesis during postnatal growth.

Catalytic activityi

ATP + sulfate = diphosphate + adenylyl sulfate.
ATP + adenylyl sulfate = ADP + 3'-phosphoadenylyl sulfate.

Pathwayi: sulfate assimilation

This protein is involved in the pathway sulfate assimilation, which is part of Sulfur metabolism.
View all proteins of this organism that are known to be involved in the pathway sulfate assimilation and in Sulfur metabolism.

Pathology & Biotechi

Involvement in diseasei

Defects in Papss2 are the cause of brachymorphism (bm), a autosomal recessive disease, which is characterized by abnormal hepatic detoxification, bleeding times and postnatal growth, such as dome-shaped skull, short thick tail, and shortened but not widened limbs. The abnormal postnatal growth has been attributed to undersulfation of cartilage proteoglycans.
