摘　　要：γ-聚谷氨酸(γ-PGA)是一种阴离子聚酰胺生物材料,由多个谷氨酸分子经γ-氨基键合而成。γ-PGA产生菌种类繁多,但本质上都是通过非核糖体依赖型的方式合成。综述了γ-PGA的性质、应用、产生菌类群、合成机制及合成酶的特点。γ-Poly-glutamic acid （γ-PGA）is an anionic polyamide biomaterial, which usually over thousands of molecules of glutamate are polymerized via γ-amide linkages. γ-PGA is found in various bacteria, and essentially synthesized in a nonribosomal manner. The characteristics, applications, producing strains, biosynthesis mechanism of γ-PGA and properties of the synthetase are briefly summarized and discussed along with the prospect in practical applications.
