Mechanism of RNA cleavage by VapC from Pyrobaculum aerophilum [PDF]

open access: yes, 2012
Proteins belonging to the PIN-domain family are widespread across bacteria, archaea and eukaryotes. PIN-domain structures are well characterised and contain three highly conserved acidic residues that are orientated to form the active site of the enzyme.

The Biology and Biochemistry of PhoH2 proteins [PDF]

open access: yes, 2013
PhoH2 proteins are found in a diverse range of organisms. To date little is known about these proteins and the role they play in the organisms in which they reside.

The Biochemistry of VapBC Toxin-Antitoxins [PDF]

open access: yes, 2011
The VapBC toxin-antitoxin (TA) systems were first identified in 2005 and little is known about their contemporary biological function, despite the fact that VapBC TAs are the largest TA family and are widespread in bacteria and archaea (Arcus, Rainey ...

Model for the regulation of the vapBC-1 locus.

open access: yes, 2013
(A) During colonization under favourable conditions, the VapBC-1 complex binds to and autorepresses TA operon transcription. (B) Stress induces Lon and Clp proteases that degrade VapB-1, releasing active VapC-1 toxin.

Neuronal activity in the primate motor thalamus during visually triggered and internally generated limb movements.

open access: yes, 1999
Single-unit recordings were made from the basal-ganglia- and cerebellar-receiving areas of the thalamus in two monkeys trained to make arm movements that were either visually triggered (VT) or internally generated (IG).

Competition binding of 50TIR and 50US by Vap proteins.

open access: yes, 2013
Gel shift products from addition of 50US substrate into samples containing 50TIR substrate and either (A) VapBC-1 or (B) VapC-1 at a 150∶1 molar ratio of VapC-1 protein to DNA. VapB-1 and VapC-1 are at a 3∶1 molar ratio in the VapBC-1 samples, but VapC-1∶

Crystal structure of the VapBC-15 complex from Mycobacterium tuberculosis reveals a two-metal ion dependent PIN-domain ribonuclease and a variable mode of toxin-antitoxin assembly

open access: yes, 2014
Although PIN (PilT N-terminal)-domain proteins are known to have ribonuclease activity, their specific mechanism of action remains unknown. VapCs form a family of ribonucleases that possess a PIN-domain assembly and are known as toxins. The activities of

VapCs of Mycobacterium tuberculosis Cleave RNAs Essential for Translation:VapCs of M. tuberculosis cleave tRNAs and 23S rRNA

open access: yes, 2016
The major human pathogen Mycobacterium tuberculosis can survive in the host organism for decades without causing symptoms. A large cohort of Toxin-Antitoxin (TA) modules contribute to this persistence. Of these, 48 TA modules belong to the vapBC (virulence associated protein) gene family. VapC toxins are PIN domain endonucleases that, in Enterobacteria,

Characterization of the VapBC-2 and VapBC-4 Toxin-Antitoxin Modules of Leptospira interrogans serovar Copenhageni.

open access: yes
Os sistemas Toxina-Antitoxina (TA) são um dos mecanismos de adaptação bacteriana a condições adversas. A bactéria L. interrogans sorovar Copenhageni estirpe Fiocruz L1-130 contém nove sistemas TA putativos, destes, foram caracterizados experimentalmente ...
