Structures of pentatricopeptide repeat proteins. [PDF]

Acta Crystallogr F Struct Biol Commun
A number of crystal, cryo‐EM and solution structures of pentatricopeptide repeat proteins have been solved, revealing details of how they interact with single‐stranded RNA and other proteins, as well as their conformational repertoire.Pentatricopeptide repeat (PPR) proteins constitute the largest family of RNA‐binding proteins in land plants, playing ...

Role of DNA superhelicity in partitioning of the pSC101 plasmid

Cell, 1990
Previous work has shown that a cis-acting locus (termed par for partitioning) on the pSC101 plasmid accomplishes its stable inheritance in dividing cell populations. We report here that the DNA of pSC101 derivatives lacking the par region shows a decrease in overall superhelical density as compared with DNA of wild-type pSC101.

Multiple structures of RNA polymerase II isolated from human nuclei by ChIP-CryoEM analysis

Nature Communications
RNA polymerase II (RNAPII) is a central transcription enzyme that exists as multiple forms with or without accessory factors, and transcribes the genomic DNA packaged in chromatin.

Research progress on molecular mechanisms of nuclear-imported transport for baculovirus proteins(杆状病毒蛋白入核转运的分子机制研究进展)

浙江大学学报. 农业与生命科学版
Baculovirus is a type of virus with a double-stranded, circular, and superhelical DNA structure. The replication and transcription of viral genes, as well as the assembly of progeny virions, occur in the nucleus of the cell. However, owing to the natural
