TRANSAMINASES, DEAMINASES AND AMINOMUTASES AND COMPOSITIONS AND METHODS FOR ENZYMATIC DETOXIFICATION

摘要

In one aspect, the invention provides methods of enzymatic detoxification of aminated toxins, e.g., mycotoxins, such as fumonisin. The invention provides methods to enzymatically detoxify plants, foods or feeds or any contaminated product or surface, including detoxification of mycotoxins, such as fumonisin, e.g., fumonisin B1 and fumonisin B2. The invention provides methods to prevent the contamination of plants, foods or feeds or any contaminated product or surface by application or a polypeptide having a deaminase activity. In one aspect, the invention relates to polypeptides having an aminotransferase, an aminomutase and/or a deaminase activity, polynucleotides encoding these enzymes, methods of making and using these polynucleotides and polypeptides.
