Amino-Acid Homopolymers Occurring in Nature PDF
Edited by Yoshimitsu Hamano
Part of the Microbiology Monographs series
Description
Microorganisms are capable of producing a wide variety of biopolymers.
Homopolymer peptides, which are made up of only a single type of amino acid, are far less ubiquitous.
The only two amino-acid homopolymers known to occur in nature are presented in this volume.
Poly-epsilon-L-lysine is a polycationic peptide and exhibits antimicrobial activity against a wide spectrum of microorganisms.
It is both safe and biodegradable and is therefore used as a food preservative in several countries.
In addition, there has been great interest in medical and other applications of poly-lysine and its derivatives. In contrast, poly-gamma-glutamic acid is an unusual anionic polypeptide.
It is also water soluble, biodegradable, edible, non-toxic and non-immunogenic and can be chemically modified to introduce various drugs.
These features are very useful for pharmaceutical and biomedical applications.
Poly-glutamic acid is also a highly attractive as a food ingredient.
