Linker-assisted engineering of chimeric xylanase-phytase for improved thermal tolerance of feed enzymes.

Biological enzymes are multifunctional macromolecules that can perform hundreds of reactions simultaneously. An enzyme must possess specific characteristics to meet industrial needs, such as stability over a wide pH and temperature range and high specific activity. A phytase and xylanase mixture is generally added to poultry feed to improve the bird's health and productivity.
