脯氨酸和缬氨酸存在于多种结构蛋白的重复基序中,在其生理功能中起着重要作用。在这里,我们合成了包含脯氨酸和缬氨酸的二肽和三肽基序的多肽。二肽乙基酯和三肽乙基酯(ValGly-OEt, GlyProGly-OEt和ValProGly-OEt)可以被木瓜蛋白酶聚合,而脯氨酸和缬氨酸乙基酯(Pro-OEt, Val-OEt)由于对木瓜蛋白酶的亲和力较差,在化学酶聚合中不具有活性。ValProGly-OEt和ValGly-OEt的共聚物为poly(ValProGly-co-ValGly),由弹性蛋白的重复序列组成,表现出类似于对偶弹性蛋白的温度依赖结构转变。聚后缩聚产物(ValProGly-co-ValGly)具有较高的分子量和类似弹性蛋白的热行为。
Proline and valine exist in repetitive motifs in various structural proteins and play an important role in their physiological functions. Herein, we synthesized polypeptides that consist of di- and tri-peptide motifs containing proline and valineviachemoenzymatic polymerization. Di- and tri-peptide ethyl esters (ValGly-OEt, GlyProGly-OEt, and ValProGly-OEt) could be polymerized by papain, whereas proline and valine ethyl esters (Pro-OEt, Val-OEt) were inactive in chemoenzymatic polymerization because of their poor affinity for papain. The copolymer of ValProGly-OEt and ValGly-OEt being poly(ValProGly-co-ValGly), which is composed of a repetitive sequence of elastin, exhibited a temperature-dependent structural transition similar to tropoelastin. The post-polycondensation product of poly(ValProGly-co-ValGly) showed higher molecular weight and elastin-like thermal behaviors.
