Characterization, localization, and sequence of F transfer region products: the pilus assembly gene product TraW and a new product, TrbI.


The traW gene of the Escherichia coli K-12 sex factor, F, encodes one of the numerous proteins required for conjugative transfer of this plasmid. We have found that the nucleotide sequence of traW encodes a 210-amino-acid, 23,610-Da polypeptide with a characteristic amino-terminal signal peptide sequence; in DNA from the F lac traW546 amber mutant, the traW… (More)
