Abstract

We report the crystal structure of mouse sulfotransferase, mSULT1D1, complexed with donor substrate 3′-phosphoadenosine 5′-phosphosulfate and accepter substrate p-nitrophenol. The structure is the first report of the native Michaelis complex of sulfotransferase. In the structure, three proposed catalytic residues (Lys48, Lys106, and His108) were in proper positions for engaging in the sulfuryl transfer reaction. The data strongly support that the sulfuryl transfer reaction proceeds through an SN2-like in-line displacement mechanism.
