Abstract
ABSTRACT The Vibrio cholerae SXT element encodes resistance to multiple antibiotics and is a conjugative, self-transmissible, and chromosomally integrating element (a constin). Excision and self-transfer of the SXT element require an element-encoded integrase. We now report that the SXT element can also mobilize the plasmids RSF1010 and CloDF13 in trans as well as chromosomal DNA in an Hfr-like manner. SXT element-mediated mobilization of plasmids and chromosomal DNA, unlike its self-transfer, is not dependent upon excision of the element from the chromosome. These results raise the possibility that the SXT element and other constins play a general role in horizontal gene transfer among gram-negative bacteria.
