Structural basis for the inhibition of RecBCD by Gam and its synergistic antibacterial effect with quinolones [PDF]

, 2016
Our previous paper (Wilkinson et al, 2016) used high-resolution cryo-electron microscopy to solve the structure of the Escherichia coli RecBCD complex, which acts in both the repair of double-stranded DNA breaks and the degradation of bacteriophage DNA ...

UiO‐66 metal–organic frameworks in biomedicine: From structural tunability to bioimaging, photodiagnostics, and photodynamic cancer therapy

FEBS Open Bio, EarlyView.
UiO‐66(Zr) metal–organic frameworks are chemically stable, biocompatible, and highly tunable nanomaterials. Their modular structure enables controlled drug delivery, multimodal bioimaging, and light‐activated photodynamic therapy, supporting integrated diagnostic and therapeutic (theranostic) applications in cancer and biomedical research.

Protocol for analyzing DNA dynamics in the presence of crowders and confined within cell-sized droplets

STAR Protocols
Summary: Here, we present a protocol for encapsulating DNA molecules under crowded conditions within cell-sized lipid-coated droplets. We describe steps for preparing a lipid-oil mixture and adding an aqueous solution containing DNA, which, when mixed ...

Machine learning-driven protein engineering: a case study in computational drug discovery

Engineering Biology, 2020
Research and development in drug discovery will need to find significant efficiency gains if the industry is to continue generating novel drugs. There is great expectation for machine learning (ML) to provide this boost in R&D productivity, but to ...

Protein cages as building blocks for superstructures

Engineering Biology, 2021
Proteins naturally self‐assemble to function. Protein cages result from the self‐assembly of multiple protein subunits that interact to form hollow symmetrical structures with functions that range from cargo storage to catalysis. Driven by self‐assembly,

Synaptic proteins promote calcium-triggered fast transition from point contact to full fusion. [PDF]

, 2012
The molecular underpinnings of synaptic vesicle fusion for fast neurotransmitter release are still unclear. Here, we used a single vesicle-vesicle system with reconstituted SNARE and synaptotagmin-1 proteoliposomes to decipher the temporal sequence of ...

All-Optical Sensing of the Components of the Internal Local Electric Field in Proteins

IEEE Photonics Journal, 2012
Here, we present a new all-optical method of interrogation of the internal electric field vector inside proteins. The method is based on experimental evaluation of the permanent dipole moment change upon excitation and the pure electronic transition ...

An unfolded protein-induced conformational switch activates mammalian IRE1. [PDF]

, 2017
The unfolded protein response (UPR) adjusts the cell's protein folding capacity in the endoplasmic reticulum (ER) according to need. IRE1 is the most conserved UPR sensor in eukaryotic cells.

Guiding AlphaFold to predict how Munc13‐1 opens Syntaxin‐1

FEBS Open Bio, EarlyView.
The syntaxin‐1 Habc‐domain (orange), linker (pink) and SNARE motif (yellow) form a closed conformation that binds to Munc18‐1 (violet) and is opened by the Munc13‐1 MUN domain (cyan) to form the SNARE complex that triggers neurotransmitter release.
