Sirtuin activators as an anti-aging intervention for longevity [PDF]

open access: yesExploration of Drug Science
Sirtuins are a family of NAD+-dependent class III histone deacetylases that regulate histones and other proteins. The mammalian sirtuins comprise seven members that have a role in energy metabolism, DNA repair, inflammation, cell survival, apoptosis ...

Transcriptional activators and activation mechanisms [PDF]

open access: yesProtein & 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.

Virtual Screening in the Identification of Sirtuins’ Activity Modulators

open access: yesMolecules, 2022
Sirtuins are NAD+-dependent deac(et)ylases with different subcellular localization. The sirtuins’ family is composed of seven members, named SIRT-1 to SIRT-7. Their substrates include histones and also an increasing number of different proteins. Sirtuins

Keeping Transcriptional Activators under Control [PDF]

open access: yes, 2006
Transcriptional activators need to be modulated and eventually switched off after the initial event that triggers their activation. Here, we discuss how ubiquitination of activators and their proteasome-mediated turnover are crucial steps in this ...

The first activation study of the β-carbonic anhydrases from the pathogenic bacteria Brucella suis and Francisella tularensis with amines and amino acids

open access: yesJournal of Enzyme Inhibition and Medicinal Chemistry, 2019
The activation of the β-class carbonic anhydrases (CAs, EC 4.2.1.1) from the bacteria Brucella suis and Francisella tularensis with amine and amino acids was investigated. BsuCA 1 was sensitive to activation with amino acids and amines, whereas FtuCA was
