Annotation score:5 out of 5

<p>The annotation score provides a heuristic measure of the annotation content of a UniProtKB entry or proteome. This score <strong>cannot</strong> be used as a measure of the accuracy of the annotation as we cannot define the 'correct annotation' for any given protein.<p><a href='/help/annotation_score' target='_top'>More...</a></p>

Sulfotransferase that utilizes 3'-phospho-5'-adenylyl sulfate (PAPS) as sulfonate donor to catalyze the sulfate conjugation of a wide variety of acceptor molecules bearing a hydroxyl or an amine groupe. Sulfonation increases the water solubility of most compounds, and therefore their renal excretion, but it can also result in bioactivation to form active metabolites. Displays broad substrate specificity for small phenolic compounds (PubMed:8447833, PubMed:7889867, PubMed:1513323). Plays an important roles in the sulfonation of endogenous molecules such as steroid hormones and 3,3'-diiodothyronin (By similarity). Mediates the sulfate conjugation of a variety of xenobiotics, including the drugs acetaminophen and minoxidil (PubMed:1513323). Mediates also the metabolic activation of carcinogenic N-hydroxyarylamines leading to highly reactive intermediates capable of forming DNA adducts, potentially resulting in mutagenesis (By similarity).By similarity3 Publications

<p>The checksum is a form of redundancy check that is calculated from the sequence.
