(E)-Methyl 3-(3,4-dihydroxyphenyl)acrylate

Acta Crystallographica Section E, 2011
The benzene ring in the title compound, C10H10O4, makes an angle of 4.4 (1)° with the C—C—C—O linker. The hydroxy groups are involved in both intra- and intermolecular O—H...O hydrogen bonds. The

1H-Benzo[d]imidazol-3-ium (Z)-3-carboxyprop-2-enoate

IUCrData, 2016
In the anion of the title molecular salt, C7H7N2+.C4H3O4−, an O—H...O hydrogen bond generates an S(7) graph-set motif while a pair of intermolecular N—H...O and C—H...O hydrogen bonds generate an R44(10) ring-motif.

The planar cell polarity protein Vangl2 interacts with the PDZ‐domains of Scribble but not with a unique PDZ‐like domain in Inturned

FEBS Letters, EarlyView.
Structural and biochemical characterisations show that the planar cell polarity (PCP) protein Inturned harbours a unique PDZ‐like domain that does not bind canonical PDZ‐binding motifs (PBMs) like that of another PCP protein Vangl2. In contrast, the apical‐basal polarity protein Scribble contains four PDZ domains that bind Vangl2, but one PDZ domain ...

2-Phenyl-N′-(2-phenylacetyl)acetohydrazide

Acta Crystallographica Section E, 2012
In the title compound, C16H16N2O2, the N′-acetylacetohydrazide group is approximately planar (r.m.s. deviation = 0.018 Å for the eight non-H atoms) and makes dihedral angles of 81.92 (6) and 65.19 (6)&#

Structural insights into an engineered feruloyl esterase with improved MHET degrading properties

FEBS Letters, EarlyView.
A feruloyl esterase was engineered to mimic key features of MHETase, enhancing the degradation of PET oligomers. Structural and computational analysis reveal how a point mutation stabilizes the active site and reshapes the binding cleft, expading substrate scope.

Hyperosmotic stress induces PARP1‐mediated HPF1‐dependent mono(ADP‐ribosyl)ation

FEBS Letters, EarlyView.
Sorbitol‐induced hyperosmotic stress rapidly induces reversible mono(ADP‐ribosyl)ation (MARylation) on PARP1 without the signs of genotoxic signaling. We show that PARP1 autoMARylation is HPF1 dependent and forms hydroxylamine‐resistant O‐glycosidic linkages.

Crystal structure of (E)-3-({6-[2-(4-chlorophenyl)ethenyl]-3-oxo-2,3-dihydropyridazin-4-yl}methyl)pyridin-1-ium chloride dihydrate

Acta Crystallographica Section E: Crystallographic Communications, 2022
In the title compound, C18H15ClN3O+·Cl−·2H2O, three intramolecular hydrogen bonds are observed, N—H...O, O—H...Cl and O—H...O. In the crystal, molecules are connected by C—H...Cl and N—H...O hydrogen bonds.

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.
