摘要:
This invention relates to phytases, polynucleotides encoding them, uses ofthe polynucleotides and polypeptides of the invention, as well as the productionand isolation of such polynucleotides and polypeptides. In particular, theinvention provides polypeptides having phytase activity under high temperatureconditions, and phytases that retain activity after exposure to high temperatures.The phytases of the invention can be thermotolerant and/or thermostable at lowtemperatures, in addition to higher temperatures. The phytases of the inventioncan be used in foodstuffs to improve the feeding value of phytate rich ingredients.The phytases of the invention can be formulated as foods or feeds or supplementsfor either to, e.g., aid in the digestion of phytate. The foods or feeds of the inventioncan be in the form of pellets, liquids, powders and the like. In one aspect, phytasesof the invention are stabile against thermal denaturation during pelleting;and this decreases the cost of the phytase product while maintaining in vivo efficacyand detection of activity in feed.
