Protein
Delta 4,5-hexuronate-2-O-sulfatase
Organism
Bacteroides thetaiotaomicron (strain ATCC 29148 / DSM 2079 / NCTC 10582 / E50 / VPI-5482)
Function
Exosulfatase involved in the degradation of the glycosaminoglycans (GAGs) chondroitin sulfate (CS), dermatan sulfate (DS) and heparan sulfate (HS). 2-O-sulfatase active on unsaturated non-reducing end hexuronate units. Has a slight preference for HS-derived structures (PubMed:25002587). GAG-specific sulfatases play a key role in the persistence of the major human gut symbiont B.thetaiotaomicron in the host gastrointestinal tract (PubMed:25002587).
Similarity
Belongs to the sulfatase family.
