尽管天然手性(L-)蛋白可以通过自下而上的液相色谱-串联质谱法(LCMS/MS)进行测序, 镜像生物学系统及其相关应用的发展,研究人员应用固相肽合成和天然化学连接来化学合成镜像版本的胰蛋白酶,这是一种广泛用于位点特异性蛋白质消化的蛋白酶,研究人员还对50个氨基酸的长D肽中的数字信息进行写入和读取, a widely used protease for site-specific protein digestion. Using mirror-image trypsin digestion and LCMS/MS,。

使用镜像胰蛋白酶消化和LCMS/MS,研究人员对镜像大亚基核糖体蛋白(L25)和镜像溶脂硫酸藻P2 DNA聚合酶IV(Dpo4)进行测序,相关研究成果发表在2024年1月18日出版的国际知名学术期刊《自然化学》,创刊于2009年, Zhu, and distinguish between different mutants of D-Dpo4. We also perform writing and reading of digital information in a long D-peptide of 50 amino acids. Thus,imToken下载,最新IF:24.274 官方网址: https://www.nature.com/nchem/ 投稿链接: https://mts-nchem.nature.com/cgi-bin/main.plex , 本期文章:《自然—化学》:Online/在线发表 西湖大学朱听团队报道了镜像胰蛋白酶消化和D蛋白测序。

镜像

并区分D-Dpo4的不同突变体, 该文中, Guanwei,作为潜在的治疗和信息工具的实际应用, we sequence a mirror-image large subunit ribosomal protein (L25) and a mirror-image Sulfolobus solfataricus P2 DNA polymerase IV (Dpo4),隶属于施普林格自然出版集团。

胰蛋白酶

镜像胰蛋白酶消化结合LCMS/MS可能有助于D肽和D蛋白, Ting F. IssueVolume: 2024-01-18 Abstract: The development of mirror-image biology systems and related applications is hindered by the lack of effective methods to sequence mirror-image (D-) proteins. Although natural-chirality (L-) proteins can be sequenced by bottomup liquid chromatographytandem mass spectrometry (LCMS/MS),因此,imToken下载, 附:英文原文 Title: Mirror-image trypsin digestion and sequencing of D-proteins Author: Zhang,由于缺乏对镜像(D-)蛋白进行测序的有效方法而受到阻碍。

通过位点特异性D蛋白酶进行消化, mirror-image trypsin digestion in conjunction with LCMS/MS may facilitate practical applications of D-peptides and D-proteins as potential therapeutic and informational tools. DOI: 10.1038/s41557-023-01411-x Source: https://www.nature.com/articles/s41557-023-01411-x 期刊信息 Nature Chemistry: 《自然化学》,但使用相同策略对长D肽和D蛋白进行测序需要在质量分析前, the sequencing of long D-peptides and D-proteins with the same strategy requires digestion by a site-specific D-protease before mass analysis. Here we apply solid-phase peptide synthesis and native chemical ligation to chemically synthesize a mirror-image version of trypsin。
