This domain, previously known as DUF1735, is found in a number of proteins mainly found in firmicutes, including BT_3987 from Bacteroides thetaiotaomicron, which displays hydrolytic activity against Hy-type N-glycans, probably initiating the degradation of this type of glycan in the human gut [1]. This domain adopts a beta-sandwich fold.	Domain
