Sulfotransferases (SULTs) are important for the metabolism of a number of drugs, neurotransmitters, and hormones, especially the steroid hormones. The cosubstrate for these reactions is 3 -phosphoadenosine 5 -phosphosulfate (PAPS) (Fig. 4.1). Like the aforementioned enzymes, sulfate conjugation typically renders the compound inactive and more water soluble. However, this process can also result in the activation of certain compounds, such as the antihypertensive minoxidil and several of the steroid hormones. Seven SULT isoforms identified in humans, including SULTs lAl to 1A3, possess activity toward phenolic substrates such as dopamine, estradiol, and acetaminophen. SULTIBI possesses activity toward such endogenous substrates as dopamine and triiodothyronine. SULTIEI has substantial activity toward steroid hormones, especially estradiol and dehydroepiandrosterone, and toward the anti-... [Pg.38]

SULT 2A and 2B sulfotransferase subfamily members sulfate the 3P-hydroxyl group of a variety of steroid hormones. Dehydroepiandrosterone (DHEA) is the prototypical substrate for the SULT 2 enzymes. However, other hydroxysteroids such as testosterone and its phase I hydroxylated derivatives are substrates for these enzymes. The SULT 2 sulfotransferases also are responsible for the sulfate conjugation of a variety of alcohols and xenobiotics that have undergone phase I hydro-xylation, including the polycyclic aromatic hydrocarbons (PAHs). The SULT 2 enzymes exhibit different patterns of tissue expression. SULT 2A1 is expressed primarily in the adrenal cortex, brain, liver, and intestine, while SULT 2B1 is expressed in the prostate, placenta, and trachea. [Pg.225]
