Abstract
The present invention relates to the field of genetic engineering, particularly to a fumonisin degrading enzyme FumDPS, gene and application thereof. The present invention provides a fumonisin degrading enzyme FumDPS from Pigmentiphaga sp. which has the amino acid sequence of SEQ ID NO: 1, has the optimum temperature of 37° C., and the optimum pH of 8 to 9, remains more than 60% of the activity in the range of pH 3 to 7, and has 100% of degradation rate of fumonisin B1 at the optimum temperature and pH. The enzyme of the present invention can be applied to reduce the harm of fumonisin to animals and human health in agriculture, feed and food.
Claims5
