Abstract

Lactoferrin (LF) exhibits multiple beneficial biological activities and thus has been used as a health food and additive. To broaden its application in the food industry, the porcine LF (pLF) gene has been engineered into rice to produce recombinant LF (rpLF) for use as a food additive. The ironbinding and antimicrobial activities of rpLF and its positive effects on early weaned piglets have been previously evaluated, yet several features, such as the signal peptide removal, glycosylation sites and antioxidant activity of rpLF, have not been fully characterized.

水稻产重组猪乳铁蛋白的表达、表征及其抗氧化活性
乳铁蛋白(LF)具有多种有益的生物活性,已被用作保健食品和添加剂。为了扩大其在食品工业中的应用,已将猪LF (pLF)基因转入水稻中,以生产重组LF (rpLF)作为食品添加剂。先前已经对rpLF的铁结合和抗菌活性及其对早期断奶仔猪的积极作用进行了评估,但rpLF的信号肽去除、糖基化位点和抗氧化活性等几个特征尚未得到充分表征。
