成分
所有胶原蛋白分子均由以三螺旋构象排列的三条肽链组成，其一级结构主要以三个氨基酸作为重复基序，即每隔两个氨基酸是一个甘氨酸残基，其前面的两个位置通常为脯氨酸或4-羟基脯氨酸。
注意
该产品应在-20℃下干燥保存，在此条件下可保持活性3年。
準備報告
该产物是通过Niyibizi, C., et al., J. Biol. Chem., 259, 14170 (1984)的胃蛋白酶提取和盐分级分离法的改进制备的。它是一种酸溶性胶原，可以溶解在水中，并添加乙酸到pH值3.0（5 mg/mL），产生乳白色无色溶液。
分析報告
SDS聚丙烯酰胺凝胶电泳在和基底膜胶原蛋白相同的还原条件下测试，得到三条主要条带。
其他說明
胶原蛋白被分为许多种结构和遗传性不同的类型。 我们使用 Bornstein和Traub提出的系统命名法。 小心不要混淆Sigma命名系统和通用的胶原蛋白分类类型。

Adhesion of Aggregatibacter actinomycetemcomitans to extracellular matrix proteins is mediated by antennae-like surface structures composed of EmaA oligomers. EmaA is an outer-membrane protein orthologous to the autotransporter YadA, a virulence determinant of Yersinia. emaA was present in the 27 strains

The human oral pathobiont Aggregatibacter actinomycetemcomitans expresses multiple virulence factors, including the trimeric, extracellular matrix protein adhesin A (EmaA). The posttranslational modification of EmaA is proposed to be dependent on the sugars and enzymes associated with O-polysaccharide (O-PS) synthesis of
