초록

Phytase(myo-inositol hexakisphosphate phosphohydro-lase;EC 3.1.38)활성은 소화기관인 소장 점막에서나 나타났고, 그 외 다른 장기에서는 alkaline phosphatase활성만을 측정할 수 있었다. 그리고 anti-90kDa phytase항혈청을 이용한 면역조직학적 조사 결과 소장 이외의 장기에서는 본 효소의 단백질 밴드가 검출되지 않았다. 이와 같은 결과 phytase는 소장에만 특이적으로 존재하며, 소장 특이적 효소의 생리적 역할로서 Phytic acid(inositol=hexakisphos-phate)를 가수분해한다. 흰쥐의 성장 발육과 더불어 phytase의 활성은 증가한다. 출생 후부터 이유기 전까지는 70kDa phytase외에도 90kDa phy-tase가 출현한다. 이 90kDa phy-tase는 이유기에 합성되는 것으로 추정된다.

The phytase(myo-inositol hexkisphosphate phosphohydrolase ; EC 3.1.3.8) activity was observed only in the homogenate of intestinal mucosa, though the activity of alkaline phisphatase was measurable in various organs. In addition, no protein bands were detected in any other organs on immunoblotting using the anti-90kDa phytase antiserum. Thses results suggest that phytase is specifically present in small intestinal mucosa, and that hydrolysis of phytic acid(inositol-hexakisphosphate) can be allotted for a physiological role of the intestine-specific enzyme. The activities of phytase was increased during development of rat. The 70kDa phytase appeared just after birth, but the 90kDa phytase was not observed until adult period, suggesting that the 90kDa phytase was synthesized in response to weanling.
