The FCT and equivalent region genes of Streptococcus pyogenes and other related bacteria encode surface proteins that include fibronectin- and collagen-binding proteins and the serological markers known as T antigens. Some of these proteins give rise to pilus-like appendages [1]. The FctA family is found in many Firmicutes and related bacteria. In S. pyogenes, the pili have a role in bacterial adherence and colonisation of human tissues [2]. Members of this family have a conserved N-terminal lysine and C-terminal asparagine that can form a covalent isopeptide bond [3].
This domain is found in Pilin from Streptococcus pyogenes and similar proteins from firmicutes and actinomycetes. Pilin is a major component of the pilus. A stack of the pilin subunits, joined by intermolecular isopeptide bonds, forms the pilus, whic ...
This domain is found in Pilin from Streptococcus pyogenes and similar proteins from firmicutes and actinomycetes. Pilin is a major component of the pilus. A stack of the pilin subunits, joined by intermolecular isopeptide bonds, forms the pilus, which is required for bacterial adhesion to host cells, for bacterial aggregation, and for biofilm formation [1]. This domain is predicted to fold into a beta-sandwich. Some members of this entry are likely to contain an intramolecular isopeptide bond connecting their N- and C-terminal strands. This family is closely related to Pfam:PF19407.
