GNPS Untargeted GC-MS Metabolomic Analysis of Essential Oils From Duguetia lanceolata and Evaluation of Antimicrobial Activity. [PDF]

Chem Biodivers
Untargeted metabolomic analysis of the essential oil of D. lanceolata leaves collected in winter revealed that they are mostly composed of sesquiterpenes, while those collected in autumn showed a predominance of monoterpenes. Both essential oils displayed antimicrobial activity against bacterial and fungal species.

NOTCH3 Mutation Causes Glymphatic Impairment and Promotes Brain Senescence in CADASIL. [PDF]

CNS Neurosci Ther
Beside mural cells, NOTCH3 is expressed in astrocytes. Expression of Aquaporin 4 (AQP4), the core mediator of glymphatic functions, is decreased in CADASIL brain. Consequently, glymphatic activities are impaired. Diminished AQP4 expression is attributed to the suppression of RUNX1‐CMYB‐AQP4 signaling due to NOTCH3 mutation in astrocytes.

Prokaryotic PfaB is a terminal acyltransferase that determines the final PUFA product. [PDF]

Protein Sci
Abstract Omega‐3 polyunsaturated fatty acids (PUFAs) are essential for human health due to their numerous beneficial biological properties. These compounds are synthesized in marine bacteria and eukaryotic microalgae by PUFA megasynthases (Pfas), which are evolutionarily related to fatty acid synthases (FAS) and polyketide synthases (PKS). In FAS, PKS,

Understanding domain swapping in the c-Src SH3 domain through hinge-loop mutagenesis. [PDF]

Acta Crystallogr D Struct Biol
The role of the hinge loop and the open interface in the 3D domain swapping of the c‐Src SH3 domain is reported.The c‐Src SH3 domain is one of the best‐characterized modular domains from a biophysical and structural point of view. This SH3 domain displays noncanonical alternative folding, forming 3D domain‐swapped oligomers and amyloid fibrils.

Fast event-based electron counting for small-molecule structure determination by MicroED. [PDF]

Acta Crystallogr C Struct Chem
Fast readout event‐based electron counting (EBEC) is a promising detection strategy to determine accurate ab initio structures of beam‐sensitive small molecules by MicroED. A fast EBEC approach enhances the dynamic range of MicroED data by limiting the likelihood of coincidence loss (CL) – the undercounting of electrons due to their spatially and ...

Crystal structures of 40- and 71-substitution variants of hydroxynitrile lyase from rubber tree. [PDF]

Acta Crystallogr D Struct Biol
Variants HNL16, HNL40 and HNL71 of hydroxynitrile lyase from Hevea brasiliensis contain 16, 40 and 71 mutations, respectively, to make increasingly larger regions surrounding the active site identical in sequence to the esterase SABP2. X‐ray structures of HNL40 and HNL71 reveal changes to the oxyanion hole and a new tunnel, which may contribute to ...

Atypical homodimerization revealed by the structure of the (S)‐enantioselective haloalkane dehalogenase DmmarA from Mycobacterium marinum

Acta Crystallographica Section D, Volume 79, Issue 11, Page 956-970, November 2023., 2023
Crystallographic structures of the (S)‐enantioselective haloalkane dehalogenase DmmarA from the waterborne pathogenic microbe Mycobacterium marinum were determined at 1.6 and 1.85 Å resolution. The structures reveal a previously unobserved mode of homodimerization, which is predominantly mediated through unusual L5‐to‐L5 loop interactions.Haloalkane ...
