Crystal structure of mouse sulfotransferase SULT1D1 complex with PAP
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 PubMedIn mammals, sulfonation as mediated by specific cytosolic sulfotransferases (SULTs) plays an important role in the homeostasis of dopamine and other catecholamines. To gain insight into the structural basis for dopamine recognition/binding, we determined the crystal structure of a mouse dopamine-sulfating SULT, mouse SULT1D1 (mSULT1D1). Data obtained indicated that mSULT1D1 comprises of a single alpha/beta domain with a five-stranded parallel beta-sheet. In contrast to the structure of the human SULT1A3 (hSULT1A3)-dopamine complex previously reported, molecular modeling and mutational analysis revealed that a water molecule plays a critical role in the recognition of the amine group of dopamine by mSULT1D1. These results imply differences in substrate binding between dopamine-sulfating SULTs from different species.
