Crystal structure of mouse cytosolic sulfotransferase mSULT1D1 complex with PAP and alpha-naphthol
Structural highlights
FunctionST1D1_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 PubMedThe mouse cytosolic sulfotransferase, mSULT1D1, catalyzes the sulfonation of a wide range of phenolic molecules including p-nitrophenol (pNP), alpha-naphthol (alphaNT), serotonin, as well as dopamine and its metabolites. To gain insight into the structural basis for its broad range substrate specificity, we solved two distinct ternary crystal structures of mSULT1D1, complexed with 3'-phosphoadenosine-5'-phosphate (PAP) plus pNP or PAP plus alphaNT. The structures revealed that the mSULT1D1 contains an L-shaped accepter-binding site which comprises 20 amino acid residues and four conserved water molecules. The shape of the accepter-binding site can be adjusted by conformational changes of two residues, Ile148 and Glu247, upon binding with respective substrates.
