Beschreibung
Zusammenfassung:	The invention provides a sheep milk casein enzymolysis polypeptide as well as a composition, a screening method and application thereof, and the amino acid sequence of the polypeptide is KPW, as shown in SEQ ID NO: 93; and/or the amino acid sequence of the polypeptide is MPLW, as shown in SEQ ID NO: 66. The half inhibitory concentration IC50 value of the polypeptide KPW is 1.86 +/-0.08 mg/mL, the half inhibitory concentration IC50 value of the polypeptide MPLW is 1.51 +/-0.06 mg/mL, and the two peptides have an inhibition effect on xanthine oxidase and have uric acid reduction activity. 本发明提供羊乳酪蛋白酶解多肽及其组合物、筛选方法和用途，所述多肽的氨基酸序列为KPW，如SEQ ID NO:93所示；和/或所述多肽的氨基酸序列为MPLW，如SEQ ID NO:66所示。本发明中多肽KPW的半抑制浓度IC50值为1.86±0.08mg/mL，多肽MPLW的半抑制浓度IC50值为1.51±0.06mg/mL，两个肽对黄嘌呤氧化酶具有抑制的效果，具有降尿酸活性。
