S. Taghavi et al., Nickel-resistance-based minitransposons: New tools for genetic manipulation of environmental bacteria, APPL ENVIR, 67(2), 2001, pp. 1015-1019
The ncc and nre nickel resistance determinants from Ralstonia eutropha-like
strain 31A were used to construct mini-Tn5 transposons. Broad host express
ion of nickel resistance was observed for the nre mini-transposons in membe
rs of the alpha, beta, and gamma subclasses of the Proteobacteria, while th
e ncc minitransposons expressed nickel resistance only in R. eutropha-like
strains.
