Synthesis and post-polymerisation functionalisation of aliphatic poly(carbonate)s [PDF]

open access: yes
This work describes the controlled organocatalytic ring-opening polymerisation (ROP) of cyclic carbonates with pendant groups for the preparation of functional aliphatic poly(carbonate)s and poly(estercarbonate) s. Their subsequent post-polymerisation

Structural and biochemical insights into the thermostable esterase Ta0887 from Thermoplasma acidophilum

open access: yesFEBS Open Bio, EarlyView.
In this study, a novel esterase from the thermoacidophilic archaeon Thermoplasma acidophilum was biochemically and structurally characterized. Our results demonstrate that Ta0887 is a highly thermostable esterase that preferentially hydrolyzes p‐nitrophenyl hexanoate and possesses an α‐helical cap domain that likely contributes to its substrate ...

The resolution of racemic 1,2-diols by the esterase catalysed hydrolysis of the corresponding cyclic carbonate

open access: yes, 1992
Racemic 1-phenyl-1,2-ethane diol can be resolved by the pig liver esterase catalysed hydrolysis of the corresponding cyclic carbonate to give the (R) and (S) 1-phenyl-1,2-ethane diol with an ee of 97 and 78 ...

The C‐terminal domain of yeast Arginyltransferase1 is essential for its catalytic activity

open access: yesFEBS Open Bio, EarlyView.
Arginyltransferase 1 (Ate1), a eukaryotic enzyme, catalyses arginylation, transferring arginine from tRNA‐Arg to the amino terminus of the target protein. Overexpression of Ate1 in yeast is lethal and is dependent on arginylation. This study elucidates how mutations in the cofactor‐binding and active site of Ate1 and truncation of its structural ...

Preparation of propylene carbonate acrylate and poly(propylene carbonate acrylate) electrolyte elastomer gels. 13C NMR evidence for Li+-cyclic carbonate interaction

open access: yes, 1995
The phosgene-free synthesis of fast curing (2-oxo-1,3-dioxolan-4-yl)methyl acrylate (propylene carbonate acrylate, PCA) is presented. Polymerization of PCA in the presence of plasticizing propylene carbonate (PC) results in the formation of reversibly ...

IGF2 knockout reduces but does not abolish osteosarcoma growth in vitro and in vivo

open access: yesFEBS Open Bio, EarlyView.
To test whether endogenous IGF2 promotes osteosarcoma growth, IGF2 was knocked out in Saos2 cells via CRISPR‐Cas9. KO cells showed reduced proliferation in vitro, and knockout xenografts in mice reached only ~25% of wild‐type tumor volume. Insulin‐like growth factor 2 (IGF2) is implicated in osteosarcoma, but direct functional evidence of its role is ...

Preparation of Magnetic Nano-Catalyst Containing Schiff Base Unit and Its Application in the Chemical Fixation of CO2 into Cyclic Carbonates

open access: yesMagnetochemistry
The development of a catalyst for the conversion of CO2 and epoxides to the corresponding cyclic carbonates is still a very attractive topic. Magnetic nano-catalysts are widely used in various organic reactions due to their magnetic separation and ...

Linear and cyclic carbamates via dialkyl carbonate chemistry

open access: yes, 2016
Dialkyl carbonates (DACs) as reagents have found recent application in phosgene-free synthesis of both linear and cyclic carbamates. Different type of catalysts have been investigated for the carbamoylation of aniline via dimethyl carbonate (DMC) in ...

Identification and characterization of a gene conferring stress resistance in Escherichia coli and cyanobacteria

open access: yesFEBS Open Bio, EarlyView.
Functional screening identified PcSyn14890, a cyanobacteria‐specific protein that enhances growth and stress resistance in E. coli and Synechocystis PCC6803. Although we expected it to function as a molecular chaperone, it was unable to protect against thermal aggregation of GAPDH.
