RrgA and RrgB Are Components of a Multisubunit Pilus Encoded by the<i>Streptococcus pneumoniae rlrA</i>Pathogenicity Islet

21 Mar 2006

Abstract excerpt

The rlrA pathogenicity islet in Streptococcus pneumoniae TIGR4 encodes three surface proteins, RrgA, RrgB, and RrgC, and three sortase enzymes. Using transmission electron microscopy, cell fractionation, cell wall sorting signal domain swapping, and Western blotting, we show that RrgA and RrgB are incorporated into a multisubunit pilus in S. pneumoniae.
