蛋白质和脂肪糖基化的生物学意义已经得到了充分的证实。例如,细胞通过改变其表面的糖链结构来响应环境刺激,而癌细胞通过重塑它们的表面糖链部分地逃避正常的生长调节。一般来说,多糖的化学性质与蛋白质、脂类、核酸和小分子代谢物的化学性质有很大的不同。因此,糖组学的进步依赖于专业分析方法的发展。糖组学是一种综合研究,目的是识别生物体中的所有多糖。质谱学(MS)正在成为糖组学领域的一项使能技术。本文综述了蛋白质糖组和糖蛋白组学工作流程的质谱学分析方法的最新进展。
The biological significance of protein and lipid glycosylation is well established. For example, cells respond to environmental stimuli by altering glycan structures on their surfaces, and cancer cells evade normal growth regulation in part by remodeling their surface glycans. In general, glycan chemical properties differ significantly from those of proteins, lipids, nucleic acids and small molecule metabolites. Thus, advances in glycomics, a comprehensive study to identify all glycans in an organism, rely on the development of specialized analytical methods. Mass spectrometry (MS) is emerging as an enabling technology in the field of glycomics. This review summarizes recent developments in mass spectrometric analysis methods for protein-based glycomics and glycoproteomics workflows.
