胶原蛋白是哺乳动物体内含量多的功能性蛋白[1]。胶原蛋白由3条α链的多肽链亚基组成,α链自身构型为左手螺旋,三条α链又互相缠绕成右手螺旋结构,即胶原蛋白的“胶原域”[2]。胶原蛋白的一级结构分析结果显示,其肽链由(Gly-X-Y)n组成,其中X通常是脯氨酸,Y通常是羟脯氨酸[3]。按照胶原蛋白发现的先后顺序,可将其分为Ⅰ型、Ⅱ型、Ⅲ型等28种胶原蛋白[4],Ⅰ型胶原蛋白分子组成为[α1(Ⅰ)]2α2(Ⅰ),主要分布于骨骼中[5];Ⅱ型胶原蛋白由[α1(Ⅱ)]3组成,主要由软骨细胞产生,因其含有大量赖氨酸残基,因而糖基化率较高[6];Ⅲ型胶原蛋白分子组成为[α1(Ⅲ)]3,因含半胱氨酸所以肽链间形成二硫键,因此其本身就可形成细纤维,Ⅲ型胶原蛋白血管中含量较高,主要存在于肺泡间质中且分布杂乱,因而形成复杂的网状结构,正是这种结构使得肺组织具有良好的柔韧性与弹性,并且可以为细胞提供充足养分,使得皮肤饱满透亮[7]。糖苷酶 F (PNGase F)是一种酰胺水解酶,经过和平空间站伊丽莎菌克隆,主要由脑膜炎脓杆菌等革兰氏阴性菌分泌。Recombinant Mouse SLAMF1/SLAM/CD150 Protein,His Tag
