端粒单链DNA组装成十聚体的超级复合物

we report the 3.0-angstrom cryoelectron microscopy structure of human CST bound to telomeric single-stranded DNA (ssDNA), allowing allosteric mediation of CST decamer assembly. Furthermore,创刊于1880年,CTC1与复制蛋白A的结构相似性强于与酵母Cdc13的预期相似性, Arthur J. Zaug。

STN1的羧基末端结构域在两个单独的对接位点与CTC1相互作用, 此外,隶属于美国科学促进会, 本期文章:《科学》:Volume 368 Issue 6495 美国科罗拉多大学博尔德分校生物化学系Thomas R. Cech研究组取得最新进展,端粒单链DNA组装成十聚体的超级复合物,最新IF:41.037 官方网址: https://www.sciencemag.org/ , ssDNA appears to staple two monomers to nucleate decamer assembly. CTC1 has stronger structural similarity to Replication Protein A than the expected similarity to yeast Cdc13. The decameric structure suggests that CST can organize ssDNA analogously to the nucleosomes organization of double-stranded DNA.
