谷氨酸的非天然异构体。水中溶解度:7 g/L (20°C)，实际上不溶于有机溶剂。D-谷氨酸适用于GR酶（谷氨酸消旋酶）及其抑制剂的结构亲和关系（SAR）研究。 D-谷氨酸是细菌肽聚糖结构的必需成分。可通过D-谷氨酸添加酶（murD）将其加入UDP-N-乙酰胞壁酰-L-丙氨酸（UDP-MurNAc-L-丙氨酸）中。然后将其掺入肽聚糖前体中。 肽聚糖构成革兰氏阳性和阴性细菌的细胞壁。通过谷氨酸消旋酶（GR）将L-谷氨酸转化为D-谷氨酸是肽聚糖合成中必不可少的步骤。 D-Glutamic acid is an essential constituent of the bacterial peptidoglycan structure. It is added to UDP-N-acetylmuramyl-L-alanine (UDP-MurNAc-L-alanine) by the enzyme D-glutamic acid-adding enzyme (murD). This is, then, incorporated into the peptidoglycan precursor. Peptidoglycan makes up the cell walls of Gram-positive and -negative bacteria. The conversion of L-glutamate to D-glutamate by glutamate racemase (GR) enzyme is an essential step in the synthesis of peptidoglycan. application： D-Glutamic acid acts as a superior to alpha ketoglutarate. It helps in the growth of Lactobacillus arabinosus. It can inhibit the IgE binding to peanut allergens. It is widely used in pharmaceuticals and foods.
