Accession ID	Name	Pfam Type
PF03631	Virulence factor BrkB	family

This family acts as a virulence factor. In Bordetella pertussis, Swiss:Q45339 is essential for resistance to complement-dependent killing by serum [1]. This family was originally predicted to be ribonuclease BN [2], but this prediction has since been shown to be incorrect [3].
