摘要: 本研究以花生为实验材料,释放花生蛋白N-糖链,并对花生蛋白N-糖链进行质谱分析,从而对花生蛋白进行深入研究。结果表明,花生总蛋白含有10条蛋白条带,并在花生总蛋白中检测到10条糖链,其糖链结构组成为H8N2,H9N2,H3N2,H3N2Xyl,H4N2,H3N2FucXyl,H4N2Xyl,H5N2,H6N2H7N2。这10条糖链均为N-糖链,且均为中性糖。本文对花生总蛋白N-糖链进行质谱分析,对花生蛋白N-糖链的研究具有重要意义。
Abstract: In this study, peanut was selected as the experimental material to release peanut protein N-glycan, and the N-glycan of peanut protein was analyzed by mass spectrometry, so as to conduct an in-depth study on peanut protein. The results showed that peanut total protein contained 10 protein bands and 10 glycan were detected in peanut total protein. The glycan was composed of H8N2,H9N2,H3N2,H3N2Xyl,H4N 2,H3N2FucXyl,H4N2Xyl,H5N2,H6N2, and H7N2. These 10 glycan all N-glycan, and they are all neutral glycan. In this paper, the total peanut protein N-glycan was analyzed by mass spectrometry, which is of great significance to the study of peanut protein N-glycan.
