Chains	Accession	Name	Description	Comments	Source
A	PF17802	Prealbumin-like fold domain (SpaA)	Prealbumin-like fold domain	This entry contains a prealbumin-like domain from a wide variety of bacterial surface proteins. This entry corresponds to domain 1 and domain 3 of SpaA from Corynebacterium diphtheriae [1]. Some members of this family contain an isopeptide bond.	Domain
A	PF20623	Sgo0707 N2 domain (Sgo0707_N2)	Sgo0707 N2 domain	This domain represents the N2 domain found in the Sgo0707 adhesin protein [1]. This domain is closely related to Pfam:PF16569.	Domain
