Molecular function

3'-phosphoadenosine 5'-phosphosulphate binding, 3'-phosphoadenylyl-sulfate binding, PAPS binding, adenosine 3'-phosphate 5'-phosphosulfate binding, phosphoadenosine phosphosulfate binding

Binding to 3'-phosphoadenosine 5'-phosphosulfate (PAPS), a naturally occurring mixed anhydride. It is an intermediate in the formation of a variety of sulfo compounds in biological systems.
