DUF5801 repeats-in-toxin domain-containing protein
This entry contains a domain that is found as tandem repeats in a number of bacterial proteins. The domain is rich in negatively charged amino acids and contains multiple potential calcium binding sites. (from Pfam)
VWA domain-containing protein
RTX calcium-binding repeat protein
enhanced entry virulence factor RtxA
This HMM describes the N-terminal, non-repetitive portion of the Legionella virulence factor RxtA, named for the presence of tandem repeats-in-toxin (RTX) domains. RtxA can be four to six thousand amino acids long. In some isolates, the toxin is divided into two tandem ORFs but presumably re-form by recombination. RtxA is involved in adherence and cell entry.
type I secretion C-terminal target domain-containing protein
This model represents a C-terminal domain associated with secretion by type 1 secretion systems (T1SS). Members of this subclass do not include the RtxA toxin of Vibrio cholerae and its homologs, although the two classes of proteins share large size, occurrence in genomes with T1SS, regions with long tandem repeats, and regions with the glycine-rich repeat modeled by PF00353.
