Abstract
The amino acid sequence of Sterol Carrier Protein2 (SCP2) isolated from rat has been investigated. Using a novel mass spectrometric mapping approach, the C-terminus was found to be extended beyond the previously published sequence. Carbohydrate analysis of SCP2 samples suggest the presence of tightly bound mannose oligosaccharide of 5-10 residues, although probably not in a glycoprotein linkage.
摘要
对从大鼠中分离出的固醇载体蛋白2（SCP2）的氨基酸序列进行了研究。采用一种新型的质谱图谱分析方法，发现其C末端比先前公布的序列更长。对SCP2样品的碳水化合物分析表明，存在由5至10个残基组成的紧密结合的甘露糖寡糖，尽管可能不是以糖蛋白连接的形式存在。
