The phy gene produces a fungal 3-phytase. This enzyme can be
utilized to increase the breakdown of plant phytates which bind
phosphorus. Phytate is the major storage form of phosphorus in many
seeds and phytate-bound phosphorus is unavailable to monogastric
animals. Since monogastric animals are not able to degrade this
molecule, much of the phosphorus bound to phytate passes into the
environment through the manure. Use of the enzyme and appropriate
management techniques can lead to a reduction in the phosphorus
content of manure, thus improving environmental conditions.
