Disease relevance of traJ

  • Using the results, a tentative map of this region of the R factor was drawn: it was essentially similar to the analogous region of the E. coli K12 F factor, except that tet was located between traJ and traA [1].

High impact information on traJ


Biological context of traJ

  • All three R factors inhibited transfer of J-independent Flac elements, indicating that they act directly on one or more genes (or products) of the transfer operon, rather than directly via traJ [3].
