The β-subunit of human thyroid stimulating hormone (hTSH) has been synthesized as a single glycoform bearing a chitobiose disaccharide at the native glycosylation site. Key to the successful completion of this synthesis was the introduction of an arginine-tagged acetamidomethyl group, which served to greatly facilitate handling of a glycopeptide fragment with poor aqueous solubility. This general solution to the challenge of working with intractable peptides is expected to find wide use in protein synthesis.
人促甲状腺激素（hTSH）的β亚基已被合成为一种单一糖型，在天然糖基化位点带有一个壳二糖二糖。成功完成该合成的关键是引入了一个带有精氨酸标签的乙酰氨基甲基基团，这极大地便于处理水溶性差的糖肽片段。这种应对难处理肽挑战的通用解决方案有望在蛋白质合成中得到广泛应用。
