Repair system for noncanonical purines in Escherichia coli.

abstract：:The ftsH gene encodes an ATP- and Zn(2+)-dependent metalloprotease which is anchored to the cytoplasmic membrane via two transmembrane segments in such a way that the very short amino- and the long carboxy termini are exposed to the cytoplasm. Deletion of the ftsH gene in Bacillus subtilis results in a pleiotropic phe...
