Abstract
The crystal and molecular structure of a dipeptide containing a blocked gamma-carboxyglutamyl (Gla) residue is presented. Two intermolecular hydrogen bonds link the amides with carbonyl groups in the dipeptide backbone, but the protected gamma-carboxy groups on the modified glutamic acid are not hydrogen bonded.
摘要
本文展示了一种含有封闭γ-羧基谷氨酸（Gla）残基的二肽的晶体和分子结构。两个分子间氢键将二肽主链中的酰胺与羰基相连，但修饰谷氨酸上受保护的γ-羧基未形成氢键。
