The invention relates to the biotechnology field, in particular to a fumonisin degrading enzyme, a coding gene, a recombinant vector, a cell, an additive and application thereof, and more specificallyrelates to the fumonisin degrading enzyme with a sequence shown as SEQ ID NO:2 or its mutant, the coding gene of the enzyme, the vector and cell containing the coding gene, the additive containing the enzyme and / or cell and / or the fermentation product thereof, application of the enzyme, the coding gene, the vector, the cell or the additive in degradation of fumonisins and / or other fungal toxins,as well as a method for degradation of fumonisin / or other fungal toxins. The enzyme provided by the invention has the advantages of: environmental friendliness, efficient and short time degradation offumonisins, and no production of harmful by-products. The enzyme can tolerate catalysis at high temperature up to 70DEG C, has low requirement for pH value and good stability, and also can degrade vomitoxin and T2 toxin to a certain degree.
