BapA prefix-like domain Two largely unrelated repetitive proteins, both named biofilm-associated protein BapA (from Salmonella enterica and from Paracoccus denitrificans) share homology domains at the two ends. Both lack a typical signal peptide for translocation by Sec, and instead depend on type I secretion for export and for contribution to biofilm formation. The conserved prefix (i.e. N-terminal) domain is shared by a number of other large, repetitive proteins of Proteobacteria thought to be associated with adhesion or biofilm formation. |
