In 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 α/β domain with a five-stranded parallel β-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.
