Protein Family Models

This entry represents the Long Rib domain that is closely related to the Pfam:PF08428 Rib domain but has a conserved insertion. These domains are found in bacterial cell surface proteins. (from Pfam)

This domain of bacterial surface proteins, about 80 amino acids long and often repeated 15 times or more in a protein sequence, is named for early described proteins such as Rib and alpha, but found in proteins with a wide variety of architectures and from various lineages.

Sequences in this family are tandem repeats of about 79 amino acids, present in up to 14 copies in a protein and highly identical, even at the DNA level, within each protein. Sequences with these repeats are found in the Rib and alpha surface antigens of group B Streptococcus, Esp of Enterococcus faecalis, and related proteins of Lactobacillus. The repeat lacks Cys residues. Most members of this protein family also have the cell wall anchor motif LPXTG shared by many staphyloccal and streptococcal surface antigens.
