Sulfatase is an enzyme that helps break down sulfate esters in various biological processes. It plays a crucial role in the metabolism of sulfated compounds, which are important for cell signaling and the formation of certain molecules in the body. Deficiencies in sulfatase can lead to various health issues, including metabolic disorders. There are several types of sulfatases, each targeting different substrates. For example, arylsulfatase specifically acts on aryl sulfate esters, while steroid sulfatase is involved in the metabolism of steroid hormones. Understanding sulfatases is important for research into genetic disorders and potential therapies.
