This entry, mainly found in Bacteroides, includes the putative surface glycan binding protein (SGBP) BT4661 from Bacteroides thetaiotaomicron (Swiss:Q89YS0). BT4661 appears to play a role in the bacterial degrading apparatus of the host glycosaminoglycans heparin (Hep) and heparan sulfate (HS). It shows six discrete domains that adopt an Ig-like fold arranged in an extended, curved conformation [1]. This is the first Ig-like domain.	Domain
