title: Inhibition of rabbit liver arylsulfatase B by phosphate esters.
abstract: Arylsulfatase B (aryl-sulfate sulfohydrolase, EC 3.1.6.1) purified from rabbit liver is competitively inhibited at modest concentrations by a variety of phosphate esters derived from amino acids, amines and simple sugars. Phospho-L-serine coupled to Sepharose 4B could be used as an affinity column to enhance the purity of a crude preparation of the enzyme. It is suggested that phosphate esters containing functional groups can be used to obtain affinity reagents to purify arylsulfatases and also to probe their active sites.
