Cover photograph (Copyright © 2012, American Society for . All Rights Reserved.): Distribution of the type IV bundle-forming pilus secretin BfpB as revealed by photoactivated localization microscopy. Recombinant Escherichia coli cells expressing BfpB-PAmCherry along with all other Bfp from the native bfp operon form autoaggregates and display an envelope distribution of BfpB-PAmCherry molecules, as shown in this falsely colored image. Each point source represents an individual BfpB molecule. These molecules are frequently arranged in clusters at nonpolar sites, where membranes of adjacent appear to overlap.
