唾液糖肽(Sialylglycopeptide, SGP)是一种复杂的双触角n聚糖,含有短肽片段,可以从鸡蛋的蛋黄中分离出来。这种天然产物作为半合成n -聚糖的原料而受到欢迎。我们发现,目前的分离方法提供的糖肽具有几种相关结构,一种是糖肽具有直接连接到肽主链的己糖,最像通过含有苏氨酸部分侧链的羟基。此外,目前的方法使用需要冻干的新鲜蛋黄,并涉及几个繁琐的纯化步骤。本文报道了一种利用固液萃取和HILIC-HPLC纯化从市售蛋黄粉中分离克量均相SGP的简便方法。
Sialylglycopeptide (SGP) is a complex bi-antennary N-glycan bearing a short peptide fragment that can be isolated from the yolk of hen eggs. This natural product has gained popularity as a starting material for the semi-synthesis of N-glycans. We have found that current isolation methods provide a glycopeptide contaminated with several related structures, one being a glycopeptide having a hexose directly attached to peptide backbone, most like through the hydroxyl containing side chain of the threonine moiety. Furthermore, current methods employ fresh egg yolks that need to be lyophilized and involve several tedious purification steps. Herein, we report a convenient method for the isolation of gram quantities of homogeneous SGP from commercially available egg yolk powder using solid/liquid extraction and HILIC-HPLC purification.
