Phosphoinositides and inositol phosphates as molecular glues

FEBS Letters, EarlyView.
Inositol phosphates (IPs) and phosphoinositides (PIPs) regulate diverse eukaryotic processes. Beyond recruiting signaling proteins or acting as structural cofactors, recent studies suggest they mediate protein–protein interactions as natural molecular glues.

N-{(Z)-3-Oxo-3-[(E)-(pyridin-2-ylmethyl)diazenyl]-1-(thiophen-2-yl)prop-1-en-2-yl}benzamide

IUCrData, 2016
In the title compound, C20H16N4O2S, the thiophene ring subtends dihedral angles of 58.6 (3) and 9.8 (3)° with the benzamide and pyridine rings, respectively, whereas these two rings are inclined to one another by 59.3 (3)°. There is an intramolecular C—H.

Site-directed mutagenesis and X-ray crystallography of two phospholipase A2 mutants: Y52F and Y73F [PDF]

, 1992
Tyr52 and Tyr73 are conserved amino acid residues throughout all vertebrate phospholipases A2. They are part of an extended hydrogen bonding system that links the N-terminal α-NH3+-group to the catalytic residues His48 and Asp99.

Three phosphatase families form a community: The phosphohydrolases that act upon inositol pyrophosphates

FEBS Letters, EarlyView.
Inositol pyrophosphates are energy‐rich signaling molecules that perform critical functions in cells. Three different families of phosphatases hydrolyze the β phosphate of the inositol pyrophosphate molecules: two have narrow specificities and one is promiscuous.

A simple adaptation to a protein crystallography station to facilitate difference X-ray scattering studies

, 2019
The X-ray crystallography station I911-2 at MAXLab II (Lund, Sweden) has been adapted to enable difference small- and wide-angle X-ray scattering (SAXS/WAXS) data to be recorded.

A light‐triggered Time‐Resolved X‐ray Solution Scattering (TR‐XSS) workflow with application to protein conformational dynamics

FEBS Open Bio, EarlyView.
Time‐resolved X‐ray solution scattering captures how proteins change shape in real time under near‐native conditions. This article presents a practical workflow for light‐triggered TR‐XSS experiments, from data collection to structural refinement. Using a calcium‐transporting membrane protein as an example, the approach can be broadly applied to study ...

Analysing the significance of small conformational changes and low occupancy states in serial crystallographic data

FEBS Open Bio, EarlyView.
This protocol paper outlines methods to establish the success of a time‐resolved serial crystallographic experiment, by means of statistical analysis of timepoint data in reciprocal space and models in real space. We show how to amplify the signal from excited states to visualise structural changes in successful experiments.
