Abstract
A novel DNA is provided which encodes an enzyme having phytase activity isolated from Penicillium. Also provided for is a method of isolating DNA encoding an enzyme having phytase activity from organisms which possess such DNA, transformation of the DNA into a suitable host organism, expression of the transformed DNA and the use of the expressed phytase protein in feed as a supplement.
