Molecular typing of IncHI plasmids provides discrimination between subgroups IncHI1, IncHI2, and IncHI3.
WebThe IncH family plasmids can produce the H-pilus, a long and flexible conjugation pilus similar to the F-pilus. Here, the pSIM-1-BJ01 possess two transfer regions, carrying the H-pilus assembly and transfer related protein genes ( trhL, trhE, traK, traB, dsbC, traV, traC, trhZ, trhO, htdA, htdK, traW, traU, traN, traD, traI, traF, traH and traG ). WebOct 10, 2014 · IncHI plasmid conjugation is thermodependent and all transfer-related genes are encoded in six operons ( tra operons).
