Crystal structure of mouse cytosolic sulfotransferase mSULT1D1 complex with PAPS/PAP and p-nitrophenol
Structural highlights
Function[ST1D1_MOUSE] Sulfotransferase with broad substrate specificity that utilizes 3'-phospho-5'-adenylyl sulfate (PAPS) as sulfonate donor to catalyze the sulfate conjugation of catecholamines, such as dopamine, prostaglandins, leukotriene E4, drugs and xenobiotic compounds. Has sulfotransferase activity towards p-nitrophenol, 2-naphthylamine and minoxidil (in vitro). Sulfonation increases the water solubility of most compounds, and therefore their renal excretion, but it can also result in bioactivation to form active metabolites.[1] [2] [3] [4] [5] Evolutionary Conservation Check, as determined by ConSurfDB.

Publication Abstract from PubMedWe 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 S(N)2-like in-line displacement mechanism.
