These are found in a variety of bacterial cell surface proteins. These proteins share a conserved motif with the Rib domain (YPDXXD). The structure of the aRib domain has been solved from two proteins, the SrpA adhesin [1] and the GspB adhesin [2]. In these proteins this domain has been termed the unique domain due to its lack of similarity to any other known structures at the time. The aRib domain from SrpA has been shown to mediate a dimer interaction [1]. This family has been added to the E-set clan based on its similarity to the Rib domain, although it does not contain the Ig fold.	Domain
A	PF20164	GspA/SrpA SigLec-like domain (GspA_SrpA_N)	GspA/SrpA SigLec-like domain	This domain is an adhesive domain that binds to sialoglycan [1]. A Thr-Arg motif conserved across homologous carbohydrate-binding adhesins that may orient the sialic acid moiety of carbohydrate ligands [1].	Domain
