摘要: Dioscorin是薯蓣(Dioscorea spp.)植物块茎中主要的贮藏蛋白, 具有块茎特异性表达的特点。研究证实它不仅有一般贮藏蛋白的特性, 该特性可能与薯蓣块茎的形成过程密切相关; 而且还有碳酸酐酶、胰蛋白酶抑制剂、抗氧化、抗高血压以及免疫调节的活性, 故薯蓣植物具有开发成功能性食品和蛋白质类医药的潜力。该文就近年来对其块茎特异蛋白的结构特征、性质和功能以及在分子生物学水平上的研究进展进行了综述。

Abstract: Dioscorins are the major tuber storage proteins of yam and have the characteristics of tuber specific expression. Dioscorins have the characteristics of general storage proteins but also exhibit biological activities, including carbonic anhydrase, trypsin inhibitor, antioxidant, antihypertensive and immunomodulatory activities. Moreover, may be involved in the formation of the yam tuber, as pharmaceutical proteins. Here we review the recent studies of dioscorin proteins, including their structural features, characterization, function and research progress in molecular biology.
