Structure of transcribing RNA polymerase II-nucleosome complex
Eukaryotic transcription requires passage of RNA polymerase II (Pol II) through chromatin, which is impaired by nucleosomes. Here the authors report the cryo-EM structure of transcribing Pol II engaged with a downstream nucleosome core particle at an ...

Template-directed biopolymerization: tape-copying Turing machines
DNA, RNA and proteins are among the most important macromolecules in a living cell. These molecules are polymerized by molecular machines. These natural nano-machines polymerize such macromolecules, adding one monomer at a time, using another linear ...

Comparative analysis of chloroplast genomes from 14 genera of Thymelaeaceae revealed variation in gene content, ranging from 128 to 142 genes, primarily influenced by IR expansion/contraction events and pseudogenization of ndhF, ndhI, and ndhG. Two large inversions were detected within the large single‐copy region, including a synapomorphic inversion ...

Central Dysmyelination in SSADH‐Deficient Humans and Mice
ABSTRACT Objectives Succinic semialdehyde dehydrogenase deficiency (SSADHD) is an inherited metabolic disorder characterized by an accumulation of γ‐aminobutyric (GABA). In addition to its synaptic role as an inhibitory neurotransmitter, GABA also plays an important role in myelination.

The elemental mechanism of transcriptional pausing. [PDF]
Transcriptional pausing underlies regulation of cellular RNA biogenesis. A consensus pause sequence that acts on RNA polymerases (RNAPs) from bacteria to mammals halts RNAP in an elemental paused state from which longer-lived pauses can arise.

ABSTRACT The pathogenesis of Sydenham chorea remains unclear. We report a 10‐year‐old girl presenting with subacute chorea and mild carditis following Streptococcal throat infection. Single‐cell RNA sequencing on 30,794 peripheral immune cells from the patient and two sex‐matched controls revealed nine immune cell clusters.

Multiple functions of the nonstructural protein 3D in picornavirus infection
3D polymerase, also known as RNA-dependent RNA polymerase, is encoded by all known picornaviruses, and their structures are highly conserved. In the process of picornavirus replication, 3D polymerase facilitates the assembly of replication complexes and ...
