Patent ID: 7022371

Claim:
An isolated phytase derived from a Penicillium species, said phytase being encoded by a nucleotide sequence capable of hybridizing to a polynucleotide sequence as shown in SEQ ID NO. 1, SEQ ID NO. 2, or SEQ ID NO: 3 under conditions of high stringency said conditions occurring about 5 to 10° C. below the melting temperature of the sequence shown in SEQ ID NO: 1, SEQ ID NO: 2 or SEQ ID NO: 3; and said phytase having one or more of the following physiochemical properties: (1) molecular weight: between about 45–60 kDa (non-glycosylated); (2) a theoretical pl of between about 7 and 7.6; (3) a pH optimum within a range of about 4.5–5.5 or (4) an ambient temperature optimum with a range of from about 40 to about 45 degree C.
