Associations of the major pseudopilin XpsG with XpsN (GspC) and secretin XpsD of Xanthomonas campestris pv. campestris type II secretion apparatus revealed by cross-linking analysis.

Abstract excerpt

The major pseudopilin XpsG is an essential component of type II secretion apparatus of Xanthomonas campestris pv. campestris. Along with other ancillary pseudopilins, it forms a pilus-like structure spanning between cytoplasmic and outer membranes.
