Combinatorial Control through Allostery [PDF]
, 2018 Many instances of cellular signaling and transcriptional regulation involve switch-like molecular responses to the presence or absence of input ligands. To understand how these responses come about and how they can be harnessed, we develop a statistical ...

A molecular mechanism for proton‐dependent gating in KcsA [PDF]
FEBS Letters, 2010 Activation gating in KcsA is elicited by changes in intracellular proton concentration. Thompson et al.[1] identified a charge cluster around the inner gate that plays a key role in defining proton activation in KcsA. Here, through functional and spectroscopic approaches, we confirmed the role of this charge cluster and now provide a mechanism of pH ...

A Fluorogenic Biosensor for Direct Detection of Vibrio vulnificus, a Climate Change Biomarker
MicrobiologyOpenVibrio vulnificus, a marine pathogen and climate change biomarker, poses serious risks to human and animal health through seafood consumption and seawater exposure. Rapid detection methods are urgently needed for both vibriosis diagnosis and surveillance

Quantum-gate implementation in permanently coupled AF spin rings without need of local fields
, 2005 We propose a scheme for the implementation of quantum gates which is based on the qubit encoding in antiferromagnetic molecular rings. We show that a proper engineering of the intercluster link would result in an effective coupling that vanishes as far ...

FEBS Letters, EarlyView.We reconstituted Synechocystis glycogen synthesis in vitro from purified enzymes and showed that two GlgA isoenzymes produce glycogen with different architectures: GlgA1 yields denser, highly branched glycogen, whereas GlgA2 synthesizes longer, less‐branched chains.

Molecular states in carbon nanotube double quantum dots
, 2006 We report electrical transport measurements through a semiconducting single-walled carbon nanotube (SWNT) with three additional top-gates. At low temperatures the system acts as a double quantum dot with large inter-dot tunnel coupling allowing for the ...

Tau acetylation at K331 has limited impact on tau pathology in vivo
FEBS Letters, EarlyView.We mapped tau post‐translational modifications in humanized MAPT knock‐in mice and in amyloid‐bearing double knock‐in mice. Acetylation within the repeat domain, particularly around K331, showed modest increases under amyloid pathology. To test functional relevance, we generated MAPTK331Q knock‐in mice.

Gated Nanosensor for Sulphate-Reducing Bacteria Detection
NanomaterialsDesulfovibrio vulgaris is an anaerobic microorganism belonging to the group of sulphate-reducing bacteria (SRB). SRB form biofilms on metal surfaces in water supply networks, producing a microbiologically influenced corrosion (MIC). This process produces

A modular design of molecular qubits to implement universal quantum gates
Nature Communications, 2016 The physical implementation of quantum information processing requires individual qubits and entangling gates. Here, the authors demonstrate a modular implementation through chemistry, assembling molecular {Cr7Ni} rings acting as qubits, with ...
