Chains	Enzyme Name	Description	Catalytic Residues
A	estrone sulfotransferase M-CSA #154	Estrogen sulfotransferase (EST) transfers the sulfate group from 3'-phosphoadenosine 5'-phosphosulfate (PAPS) to the phenolic oxygen of estrogenic steroids. EST plays a role in many carcinogenic processes, with polymorphism implicated in genetic risk towards some cancers.
