(10) The H-N-H motif is the 30-33 amino acids consensus sequence containing two pairs of conserved histidines surrounding a conserved asparagine and found in various nucleases including E-group DNase colicins such as colicin E7 (32), and E9 (33) and homing endonucleases (34).
These include the bacteriocins from gram-positive bacteria, the colicins [4], the microcins, and the bacteriocins from Archaea.
coli of intestinal origin are also known to produce colicins and microcins that have similar barrier effect against other pathogenic E.
coli, are known to release colicins into the intestinal lumen, which inhibit the proliferation of other bacteria (Drasar & Hill 1974).
The significant progress in antimicrobial metabolite research was made by investigating the colicins. Those prototype peptidyl metabolites are produced by most species of the Enterobacteriaceae family and this has resulted in considerable in-depth knowledge on the genetic background, structure, synthesis and mode of action of these molecules (Messaoudi et al., 2013; Settanni and Corsetti, 2008).
