Abstract
Antimicrobial peptides, which constitute an important component of innate immunity in animal and plant kingdom, are ubiquitously distributed in nature. However, they differ widely in their sizes, sequences and structures. On the basis of their structure they have been broadly classified into three classes: a) linear peptides with propensity for amphiphilic a-helical structure, b) peptides with β or αβ structure stabilized by different number of disulfide bridges and c) peptides with over-representation of certain amino acids or unusual structures. Although considerable amount of work has been done on peptides of all the three classes, recent reviews have emphasized on peptides belonging to the first two classes. The present review focuses on the peptides belonging to the third group. The antimicrobial peptides discussed in this article include aromatic amino acid-rich peptides, (Pro-Arg)-rich peptides, unusual defensins and defensin-like molecules, unusual antimicrobial peptides from amphibians, bacteriocins with unusual structure and anionic antimicrobial peptides.
Keywords: Aromatic amino acid-rich peptides, PR-rich peptides, Unusual defensins and defensin-like peptides, Unusual antimicrobial peptides from amphibians, Bacteriocins with unusual structures, Anionic antimicrobial peptides

Chalcogen-modified nucleic acid analogues
Chalcogen-modified nucleosides, nucleotides and oligonucleotides have been of great interest to scientific research for many years. The replacement of oxygen in the nucleobase, sugar or phosphate backbone by chalcogen atoms (sulfur, selenium, tellurium) gives these biomolecules unique properties resulting from their altered physical and chemical properties. The continuing interest in ...read more
