Sulfated glycans are ubiquitous nutrient sources for microbial communities that have co-evolved with eukaryotic hosts. Bacteria metabolise sulfated glycans by deploying carbohydrate sulfatases that remove sulfate esters. Despite the biological importance of sulfatases, the mechanisms underlying their ability to recognise their glycan substrate remain poorly understood. Here, we utilise structural biology to determine how sulfatases from the human gut microbiota recognise sulfated glycans. We reveal 7 new carbohydrate sulfatase structures span four S1 sulfatase subfamilies. Structures of S1_16 and S1_46 represent the first structures of these subfamilies. Structures of S1_11 and S1_15 demonstrate how non-conserved regions of the protein drive specificity towards related but distinct glycan targets. Collectively, these data reveal that carbohydrate sulfatases are highly selective for the glycan component of their substrate. These data provide new approaches for probing sulfated glycan metabolism, whilst revealing the roles carbohydrate sulfatases play in host-glycan catabolism.
