Structure/function of ATP sulfurylase domain of human 3'-phosphoadenosine 5'-phosphosulfate synthase (hPAPSS)
{{output}}
3'-phosphoadenosine 5'-phosphosulfate (PAPS) is synthesized by PAPS synthase (PAPSS) in two steps. In the first step ATP sulfurylase (ATPS) transfers sulfate group onto adenylyl moiety of ATP to form adenosine 5'-phosphosulfate (APS) and PPi. APS-kinase (APSK)... ...
