Transcriptional activators and activation mechanisms [PDF]
Protein & Cell, 2007 Transcriptional activators are required to turn on the expression of genes in a eukaryotic cell. Activators bound to the enhancer can facilitate either the recruitment of RNA polymerase II to the promoter or its elongation. This article examines a few selected issues in understanding activator functions and activation mechanisms.

Septentrio Conference Series, 2020 First year architecture students are introduced to the library by taking part in an “Escape Room” activity in the KTH library. The aim of this initiative is to introduce the students to the library space and the library's resources in an interactive and playful way and to enable them to learn and reflect upon their learning within the frame of an ...

Active colloidal molecules in activity gradients [PDF]
Physical Review E, 2022 We consider a rigid assembly of two active Brownian particles, forming an active colloidal dimer, in a gradient of activity. We show analytically that depending on the relative orientation of the two particles the active dimer accumulates in regions of either high or low activity, corresponding to, respectively, chemotaxis and antichemotaxis.

ChemElectroChem, 2022 In this work, we systematically investigate the ‘catalytic’ graphitization of a biomass precursor (coffee ground) using 10–60 wt. % of the activator iron (III) chloride hexahydrate in a temperature range of 1000 °C – 2400 °C.

Alkyl derivative of p-terphenyl as an activator of polysiloxane-based scintillator [PDF]
Ядерна фізика та енергетика, 2022 One of the problems in creating a radiation-hard scintillation composition on a polysiloxane base is the search for a radiation-hard activator capable of dissolving in such a base in sufficient quantity.

Journal of Enzyme Inhibition and Medicinal Chemistry, 2017 Identifying possible new biological activities of psychoactive substances belonging to various chemical classes may lead to a better understanding of their mode of action and side effects. We report here that amines structurally related to amphetamine, a

Activation of β- and γ-carbonic anhydrases from pathogenic bacteria with tripeptides
Journal of Enzyme Inhibition and Medicinal Chemistry, 2018 Six tripeptides incorporating acidic amino acid residues were prepared for investigation as activators of β- and γ-carbonic anhydrases (CAs, EC 4.2.1.1) from the pathogenic bacteria Vibrio cholerae, Mycobacterium tuberculosis, and Burkholderia ...

Human Sirtuin Regulators: The “Success” Stories
Frontiers in Physiology, 2021 The human sirtuins are a group of NAD+-dependent protein deacylases. They “erase” acyl modifications from lysine residues in various cellular targets including histones, transcription factors, and metabolic enzymes. Through these far-reaching activities,

Accurate timekeeping is controlled by a cycling activator in Arabidopsis. [PDF]
, 2013 Transcriptional feedback loops are key to circadian clock function in many organisms. Current models of the Arabidopsis circadian network consist of several coupled feedback loops composed almost exclusively of transcriptional repressors.
