Full crystallographic information is available from OCA. For a guided tour on the structure components use FirstGlance. Ligands: ADX, K Gene: PAPSS1, ATPSK1, PAPSS (HUMAN) Activity: Sulfate adenylyltransferase, with EC number 2.7.7.4 Resources: FirstGlance, OCA, PDBe, RCSB, PDBsum Function [PAPS1_HUMAN] 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. Also involved in the biosynthesis of sulfated L-selectin ligands in endothelial cells. Evolutionary Conservation Check, as determined by ConSurfDB.
