This is a family of beta-barrel porin-like outer membrane proteins from enteropathogenic Gram-negative bacteria. Intimins and invasins are virulence factors produced by pathogenic Gram-negative bacteria. They carry C-terminal extracellular passenger domains that are involved in adhesion to host cells and N-terminal beta domains that are embedded in the outer membrane. This family represents the beta-barrel porin-like domain in the outer membrane that can be found in intimins, invasins and some inverse autotransporters [1,2].	Domain
A, B	PF07979	Intimin C-type lectin domain (Intimin_C)	Intimin C-type lectin domain	This domain is found at the C-terminus of intimin. Its structure has been solved and shown to have a C-lectin type of structure [1]. Intimin is a bacterial adhesion molecule involved in intimate attachment of enteropathogenic and enterohemorrhagic Es ...	This domain is found at the C-terminus of intimin. Its structure has been solved and shown to have a C-lectin type of structure [1]. Intimin is a bacterial adhesion molecule involved in intimate attachment of enteropathogenic and enterohemorrhagic Escherichia coli to mammalian host cells. Intimin targets the translocated intimin receptor (Tir), which is exported by the bacteria and integrated into the host cell plasma membrane.	Domain
A, B	PF01476	LysM domain (LysM)	LysM domain	The LysM (lysin motif) domain is about 40 residues long. It is found in a variety of enzymes involved in bacterial cell wall degradation [1]. This domain may have a general peptidoglycan binding function. The structure of this domain is known [2].	Domain
A, B	PF02369	Bacterial Ig-like domain (group 1) (Big_1)	Bacterial Ig-like domain (group 1)	This family consists of bacterial domains with an Ig-like fold. Members of this family are found in bacterial surface proteins such as intimins and invasins involved in pathogenicity.	Domain
