“…Sulfotransferases catalyze the transfer of a sulfuryl group, SO,, from 3'-phosphoadenosine 5'-phosphosulfate (PAPS) to compounds bearing amino or hydroxyl groups, thus forming the corresponding sulfamates or sulfate esters, respectively. Cytosolic sulfotransferases have been described with specificities for phenols (EC 2.8.2.1; Baranczyk-Kuzma and Szymczyk, 1986; , tyrosine-ester (Rens-Domiano and Roth, 19891, alcohols (Lyon and Jakoby, 19801, amines (Ramaswamy and Jakoby, 1987a), estrone and steroids (Adams and McDonald, 1981;Hobkirk et al, 1989), cholesterol (Epstein et al, 1984), and bile salts (Barnes et al, 1986). This study is focused on the phenol, or aryl, sulfotransferase (PST) as expressed in a bovine airway cell culture system.…”
