Sulfotransferase 1C2

Definition:

Sulfotransferase that utilizes 3'-phospho-5'-adenylyl sulfate (PAPS) as sulfonate donor to catalyze the sulfate conjugation. Sulfonates p-nitrophenol, a small phenolic compond. Does not sulfonate steroids, dopamine, acetaminophen, or alpha-naphthol. Catalyzes the sulfonation of the carcinogenic N-Hydroxy-2-acetylaminofluorene leading to highly reactive intermediates capable of forming DNA adducts, potentially resulting in mutagenesis.
