紫球藻蛋白和活性肽的研究进展

Advances in Studies on Proteins and Active Peptides of Porphyridium creuntum

紫球藻(Porphyridium creuntum)是一类单细胞的海洋微藻,属于红藻门。紫球藻富含水溶性藻胆蛋白,尤其是藻红蛋白,后者是紫球藻色素的来源。藻胆蛋白是一类具有多种生物活性的捕光蛋白,已被广泛应用于食品、化妆品等领域,亦可作为荧光探针和光敏剂用于科研和医学领域。综述了紫球藻蛋白的分类特征、分离纯化以及紫球藻蛋白和小分子多肽的活性和应用现状,为寻找紫球藻新型蛋白和活性肽提供参考依据。

Porphyridium creuntum is a single-celled marine microalga belonging to the Rhodophyta.It’s rich in water-soluble Phycobiliprotein,especially Phycoerythrin,which is the source of pigment in Porphyridium creuntum.Phycobiliprotein is light-catching protein with various biological activities.It has been widely used in food,cosmetics and other fields.It can also be used as fluorescent probe and photosensitizer in scientific research and medicine.In this paper,the classification,purification and activity of protein and small molecule polypeptide of Porphyridium creuntum are reviewed.It provides a reference for the search for new proteins and active peptides of Porphyridium creuntum.
