Organic selenide and bio-enzyme catalysis system and method for synthesizing organic selenide

The invention belongs to the technical field of synthetic biology, and relates to an organic selenide and a biological enzyme catalysis system and method for synthesizing the organic selenide. The invention relates to a method for synthesizing an organic selenide, which adopts sodium hydrogen selenide as a selenium donor, and synthesizes the organic selenide through a sulfur carrier protein mediated biosynthesis route. The sulfur carrier protein-mediated biosynthetic pathway comprises a sulfur carrier protein-mediated L-cysteine biosynthetic pathway, a sulfur carrier protein-mediated thiamine biosynthetic pathway, or a sulfur carrier protein-mediated creatinamycin biosynthetic pathway. According to the method, green biosynthesis of the organic selenide is achieved through biological enzyme catalysis, the problems that in chemical synthesis, selectivity is poor, products are not specific and pollutants are discharged can be solved, meanwhile, the method has certain universality, and a brand-new green biologica
