Info. needed on "suicide" gene for coli

[Pramathesh S. Patel]

Hi,
	I am interested in getting info. regarding any gene I could use
as a "suicide" gene in E. coli (i.e.. expression of a particular gene
causes cell death).  I have tried the mammalian GATA-1 gene and the 
Bacillus sacB gene.  Unfortunately, I have had no success.
	Any help will be appreciated.  Thanks in advance.
