Forest floor and soil arylsulphatase: hydrolysis of tyrosine sulphate, an environmentally relevant substrate for the enzyme. [pdf]Paper  abstract   bibtex   
Arylsulphatase is an enzyme widespread in nature that catalyzes the release of SO4 from sulfate esters of simple phenols. Although this enzyme is found extensively in soil, its activity has not been successfully correlated with S mineralization rates. A typical assay substance is not found in nature. Various tests show that microbial growth was necessary to sustain enzyme production and activity while fungal growth was not.
