PF16364 | Cell surface antigen C-terminus (Antigen_C) | Cell surface antigen C-terminus | This repeated domain is found at the C-terminus of cell surface antigens [1-3]. In the Streptococcus mutans antigen I/II there are three repeats of this domain, a cleft between the first two of these forms a binding site for the human salivary agglut ... | Domain | |
PF17998 | Cell surface antigen I/II C2 terminal domain (AgI_II_C2) | Cell surface antigen I/II C2 terminal domain | This is the second domain (C2) located in the C-terminal region found in antigen I/II type adhesin protein AspA from S. pyogenes. Together with C3, these two domains form an elongated structure, each domain adopts the DEv-IgG fold. Similar to the cla ... | Domain |
