Abstract

Mutated Pseudomonas aeruginosa sulfatase (PaS) enzymes with enhanced enzymatic activity as compared to the parental wild type enzyme are provided. The variant sulfatases of the invention advantageously allow for accurate analysis of bodily samples for the presence of drugs. Methods of using the mutated enzymes for hydrolysis of sulfate ester linkages are also provided, including with substrates such as opioids or steroids containing a sulfate ester linkage.
