Protein Variants

EC Number Protein Variants Comment Organism
3.1.6.8 C69A The inactive mutant in complex with p-nitrocatechol sulfate mimics a reaction intermediate during sulfate ester hydrolysis by the active enzyme, without the covalent bond to the key side-chain C-alpha-formylglycine Homo sapiens
3.1.6.8 C69S the mutant is able to bind covalently to the substrate and hydrolyse it, but is unable to release the resulting sulfate Homo sapiens
