Formation and dissociation of enzyme complexes comprising rSULT1A1 (E), OHPCB (ROH), and PAP. Kd (A), (B), (C), and (D) indicate the dissociation constants for PAP binding to rSULT1A1, OHPCB binding to rSULT1A1, OHPCB binding to the enzyme-PAP complex, and PAP binding to an enzyme-OHPCB complex, respectively.
