The layout of this reaction may differ from that in the pathway view due to the constraints in pathway layout
PAP is generated as a byproduct of sulfonation reactions in vivo; its hydrolysis to AMP and orthophosphate returns its constituents to the pool of molecules available for cytosolic nucleotide metabolism. Bisphosphate 3'-nucleotidase 1catalyzes this reaction efficiently in vitro; whether other nucleotidases also play a role in PAP breakdown in vivo is unknown.
