Rib/alpha-like repeat. The region featured in this family is found repeated in a number of bacterial surface proteins, such as Rib and alpha. These are expressed by group B streptococci, and Rib is thought to confer protective immunity.

Sialidase, N-terminal domain.

Rib/alpha/Esp surface antigen repeat. 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.

Glucan-binding domain (YG repeat) [Carbohydrate transport and metabolism].

PspC-related protein choline-binding protein 1. Members of this family share C-terminal homology to the choline-binding form of the pneumococcal surface antigen PspC, but not to its allelic LPXTG-anchored forms because they lack the choline-binding repeat region. Members of this family should not be confused with PspC itself, whose identity and function reflect regions N-terminal to the choline-binding region. See Iannelli, et al. (PMID: 11891047) for information about the different allelic forms of PspC.
