Fertility inhibition of RP1 by IncN plasmid pKM101.
IncN plasmids, including pKM101, strongly inhibit the conjugal transfer of cohabiting IncP plasmids. We localized the pKM101 DNA sufficient for this phenomenon to a 1.1-kilobase region (denoted fip). Two fip-deficient Tn5 insertion derivatives of pKM101 were isolated; neither affected other pKM101-mediated functions. fip did not inhibit either the synthesis of the IncP plasmid's sex pilus or its ability to mediate entry exclusion against other IncP plasmids.
