  A novel γ-glutamyltranspeptidases (GGT) for the synthesis of poly-γ-glutamic acid (γ-PGA) is presented. Soil samples from the mangrove sediment were collected. One strain designated L-12 was identified whose cell extract could convert glutamine into γ-PGA. The 16S rDNA gene analysis of L-12 revealed its phylogenetic relatedness to Bacillus cereus. The GGT produced by L-12 was purified 20.3-fold. The optimum pH and temperature for γ-PGA synthesis by this GGT were 7.5 and 20°C, respectively. The results indicated that L-12 could be used as a novel bacterial GGT source for synthesizing γ-PGA production. To our knowledge, this is the first report for GGT to γ-PGA biosynthesis.
