Nuclear‐Spin Hyperpolarization of Biomolecules by Optically Enhanced NMR at Ultra‐High Field

open access: yesJournal of the Chinese Chemical Society, EarlyView.
This study shows that the sensitivity of liquid‐state NMR spectroscopy can be dramatically increased, with enhancement factors up to 160‐fold on a 1.1 GHz ultra‐high‐field NMR spectrometer. This advance exploits low‐concentration photochemically induced dynamic nuclear polarization (LC‐photo‐CIDNP) and it enables facile atomic‐resolution detection of ...

Structural Insights Into the Function of Leishmania major Adenylosuccinate Lyase

open access: yesProteins: Structure, Function, and Bioinformatics, EarlyView.
ABSTRACT One of several intriguing aspects of kinetoplastid biochemistry is the complete dependence on host purines and purine recycling due to the lack of a de novo purine biosynthesis pathway. Adenylosuccinate lyase (ASL, EC 4.3.2.2) is a key enzyme in the purine synthesis pathway responsible for the conversion of adenylosuccinate into adenosine ...

Structural and Biochemical Characterization of the Diaminopimelate Epimerase DapF From Pseudomonas aeruginosa PA14

open access: yesProteins: Structure, Function, and Bioinformatics, EarlyView.
ABSTRACT The emergence of antibiotic resistance in bacteria is a major threat to global public health. To combat increasingly drug‐resistant bacteria like Pseudomonas aeruginosa, new targets for pharmaceuticals need to be explored. One such potential target for P.

Structural and Stability Analysis of de Novo Designed Proteins Incorporating a Plant Self‐Incompatibility Motif

open access: yesProteins: Structure, Function, and Bioinformatics, EarlyView.
ABSTRACT Artificial protein design enables the creation of stable scaffolds beyond those evolved in nature. Incorporation of native functional motifs into de novo scaffolds provides a promising strategy to mimic natural interactions while altering structural frameworks.

Large‐Scale Structural Dynamics in the Tail Fiber Modulate the Infective Transition of the T7 Bacteriophage

open access: yesSmall, EarlyView.
During host recognition, the fibers of T7 bacteriophages transition from a capsid bound state to an extended conformation, which requires some level of fiber flexibility. By using high‐speed atomic force microscopy, we show that the fibers have an internal molecular hinge and a torsionally compliant coiled‐coil region.

Discriminating Between Living and Dead Bacteria With a Field‐Effect Transistor Based on Nano‐Channels

open access: yesSmall, EarlyView.
Bacterial viability is determined in a complex environment with a field‐effect biological transistor with a limit of detection of a single bacterium. Living, antibiotic‐treated, thermally denatured, and inhibited E. coli generate distinct electrical signatures, enabling label‐free single‐cell detection and providing new opportunities for rapid ...

Symmetry‐Guided Optical Control of Dynamic 1D Protein Self‐Assembly and Precise In Vitro Initiation of Biomolecular Condensation

open access: yesSmall, EarlyView.
A photoreversible 1D protein assembly has been developed by utilizing symmetry matching between StrepTactin and photoswitchable Dronpa145N. The light‐induced modulation of oligomerization allows for precise control over protein connectivity and valency.
