Abstract: L-glutamate oxidase (GLOD) is a flavin protease with FAD for cofactor, and specifically catalyzes the reaction that one mole of L-glutamic acid was converted to one mole of hydrogen peroxide, α-ketoglutaric acid and ammonia with the consumption of one mole of oxygen and water. It has been widely used in the area of food, medicine, fermentation, etc. In this overview, several research aspects of GLOD are summarized, including microbial sources, enzymatic properties, fermentation conditions, purification and analytical applications of the enzyme. In addition, the research prospects of the L-glutamate oxidase are proposed.
Key words: L-glutamate oxidase; enzymatic properties; express conditions; purification; application; research prospect
