Chains	Accession	Name	Description	Comments	Source
A	PF00345	Pili and flagellar-assembly chaperone, PapD N-terminal domain (PapD_N)	Pili and flagellar-assembly chaperone, PapD N-terminal domain	C2 domain-like beta-sandwich fold. This domain is the n-terminal part of the PapD chaperone protein for pilus and flagellar assembly.	Domain
B	PF05229	Spore Coat Protein U domain (SCPU)	Spore Coat Protein U domain	This domain is found in a bacterial family of spore coat proteins [1], as well as a family of secreted pili proteins involved in motility and biofilm formation ([2]). This family is distantly related to fimbrial proteins.	Domain
