The crystal structure of Thermus transcription activation complexes containing the transcriptional activator CarD reveals a new mechanism for the activation of transcription.
The crystal structure of bacterial RNA polymerase bound to the transcription bubble reveals key features that support the formation of a double-strand/single-strand DNA junction at the upstream edge of the −10 element where bubble formation initiates.
An inorganic tin oxochloride cluster specifically binds to an intrinsically disordered, histidine-rich, low complexity protein region and arrests de novo transcription initiation without affecting reinitiation.

Enzyme evolution is reversible on a structural and functional (phenotypic) level, but through a different mutational pathway that leads to genotypic incompatibility with the ancestor.
Proteasome-mediated degradation of the TATA-box binding protein (TBP) during terminal differentiation is regulated by the E3 ligase Huwe1 and the deubiquitinase USP10.

The acquisition of new foreign DNA by the prokaryotic adaptive immune system CRISPR-Cas is shown to depend on the fundamental sequence specificity of the Cas1 integrase.

A new unfolded protein response has been discovered that is distinct from the heat shock response and protects mammalian cells from proteotoxic stress.
