The type IV bundle-forming pili (BFP) of enteropathogenic Escherichia coli (EPEC) are required for virulence in orally challenged human volunteers and for the localized adherence and autoaggregation in vitro phenotypes. BFP filament biogenesis and fu

Production of type IV bundle-forming pili (BFP) by enteropathogenic Escherichia coli (EPEC) requires the protein products of 12 genes of the 14-gene bfp operon. Antisera against each of these proteins were used to demonstrate that in-frame deletion o

Production of type IV bundle-forming pili by enteropathogenic Escherichia coli (EPEC) requires BfpB, an outer-membrane lipoprotein and member of the secretin protein superfamily. BfpB was found to compose a ring-shaped, high-molecular-weight outer-me

The bundle-forming pili (BFP) of enteropathogenic Escherichia coli are believed to play a role in pathogenesis by causing the formation of bacterial microcolonies that bind epithelial surfaces of the small intestine. This in vivo process is mimicked

This review describes the current state of biocatalysis in the chemical industry. Although we recognize the advantages of chemical approaches, we suggest that the use of biological catalysis is about to expand dramatically because of the recent devel

The signal transduction pathway that mediates the response of haploid yeast cells to peptide mating pheromones involves several components including the protein kinases STE7 and STE11. We have isolated and characterized a dominant allele of the STE11

This work describes a multifunctional phage lambda expression vector system, lambda YES, designed to facilitate gene isolation from eukaryotes by complementation of Escherichia coli and Saccharomyces cerevisiae mutations. lambda YES vectors have a se

Type IV bundle-forming pili of enteropathogenic Escherichia coli are required for the localized adherence and autoaggregation phenotypes. Whether these pili are also required for virulence was tested in volunteers by inactivating bfpA or bfpT ( perA

Sequence flanking the bfpA locus on the enteroadherent factor plasmid of the enteropathogenic Escherichia coli (EPEC) strain B171-8 (O111:NM) was obtained to identify genes that might be required for bundle-forming pilus (BFP) biosynthesis. Deletion
