Abstract

Two novel chitin-binding peptides, designated Pp-AMP 1 and Pp-AMP 2, which had antimicrobial activity against pathogenic bacteria and fungi, were purified from Japanese bamboo shoots (Phyllostachys pubescens) by a simple procedure based on chitin affinity chromatography. They had the common structural features of the plant defensin family, but they could not be grouped in any type of that family. They showed a high degree of homology to mistletoe toxins.
