SULT1A1 (sulfotransferase family 1A member 1) is a phase II metabolic enzyme that plays a critical role in the sulfonation of various endogenous and exogenous compounds. This cytosolic enzyme catalyzes the transfer of a sulfonate group from the universal donor 3'-phosphoadenosine-5'-phosphosulfate (PAPS) to hydroxyl or amine groups of substrates, including hormones, neurotransmitters, drugs, and environmental xenobiotics. Sulfonation generally enhances the water solubility of these molecules, facilitating their excretion, but can also bioactivate certain procarcinogens.
Recombinant SULT1A1 protein is engineered using expression systems like *E. coli* or mammalian cells to enable large-scale production for biochemical and pharmacological studies. Its structure, comprising approximately 295 amino acids, adopts a conserved sulfotransferase fold with a central α/β core. Key residues, such as His108 in the active site, are critical for substrate binding and catalytic activity. The enzyme functions as a dimer, with conformational flexibility influencing substrate specificity.
Research applications of recombinant SULT1A1 include drug metabolism studies, toxicology assessments, and investigations into hormone regulation. It is highly expressed in the liver, intestine, and platelets, making it relevant to interindividual variability in drug responses. Genetic polymorphisms (e.g., the common *SULT1A1* Arg213His variant) can reduce enzyme stability and activity, impacting metabolic pathways and disease susceptibility. In cancer research, SULT1A1 overexpression is linked to hormone-dependent cancers, as it modulates estrogen and thyroid hormone signaling.
The availability of recombinant SULT1A1 has advanced precision medicine by enabling in vitro models to predict metabolic interactions and personalize therapies based on genetic profiles. Its role in detoxification and bioactivation continues to inform drug development and chemical safety evaluations.
