摘要：
The present teachings provide modified enzymes, preferably phytases, which have increased stability, hypothesized to arise from increased glycosylation. The enzymes can be modified to introduce or increase the number of glycosylation sites in the amino acid sequence, or glycosylation can be increased by the use of specific host production methods, or both. The enzymes of the present teachings have an increased stability after treatment at elevated temperature, which can be measured by inactivity reversibility or percent recovery following a treatment such as heating. The enzymes of the present teachings find application for example in food, feed, and feed pelleting.
