Highlights
Molecules isolated from bacteria that have demonstrated bactericidal activity are called bacteriocins
Two peptide bacteriocins are unique as, two genes encoding each of the peptides are located next to each other and both of the peptides are required for bactericidal activity
Lantibiotics are produced by a large number of Gram positive bacteria such as Streptococcus and Streptomyces to attack other gram positive bacteria and as such they are considered a member of the bacteriocins [3]
Summary
Introduction Molecules isolated from bacteria that have demonstrated bactericidal activity are called bacteriocins. Synthesized peptide bacteriocins from Gram-positive bacteria can be subdivided into two major classes. Type A lantibiotics are characterized by being strongly cationic (with 2 to 7 net positive charge), having molecular masses more than 2100 Da, and having rigid ring conformations separated by areas of flexibility [1].
