Mass Spectrometry in the Elucidation of the Glycoproteome of Bacterial Pathogens [PDF]

, 2010
Presently some three hundred post-translational modifications are known to occur in bacteria in vivo. Many of these modifications play critical roles in the regulation of proteins and control key biological processes.

Smart Organic–Inorganic Copolymer Nanoparticles Distinguish Between Microglia and Cancer Cells for Synergistic Immunotherapy in Glioma

Advanced Science, EarlyView.
The tumor microenvironment‐responsive nanoagonists are developed using an organic–inorganic copolymer composed of the polymer (PC6AB) and manganous phosphate ionic oligomers (MnP). PC6AB with membranolytic activity selectively interacts with tumor cell membranes to induce immunogenic cell death, while MnP activates the STING pathway in immune cells ...

Molecular Dynamics Simulation of Sympathetic Crystallization of Molecular Ions

, 2003
It is shown that the translational degrees of freedom of a large variety of molecules, from light diatomic to heavy organic ones, can be cooled sympathetically and brought to rest (crystallized) in a linear Paul trap.

Mass Spectrometry-based Methods for Phosphorylation Site Mapping of Hyperphosphorylated Proteins Applied to Net1, a Regulator of Exit from Mitosis in Yeast [PDF]

, 2002
Prior to anaphase in Saccharomyces cerevisiae, Cdc14 protein phosphatase is sequestered within the nucleolus and inhibited by Net1, a component of the RENT complex in budding yeast. During anaphase the RENT complex disassembles, allowing Cdc14 to migrate

Identification and Application of a Novel Patulin Degrading Enzyme From Meyerozyma guilliermondii

Advanced Science, EarlyView.
Patulin (PAT), a hazardous mycotoxin, threatens human health. A novel yeast‐derived short‐chain dehydrogenase/reductase effectively degrades PAT into nontoxic ascladiol via catalytic triad activity. The biological detoxification process has no significant effect on the quality of fresh pear juice.

HDAC6 and USP9X Control Glutamine Metabolism by Stabilizing GS to Promote Glioblastoma Tumorigenesis

Advanced Science, EarlyView.
Glioblastoma (GBM) growth relies on glutamine synthetase (GS), which is stabilized by histone deacetylase 6 (HDAC6) and deubiquitinated by ubiquitin‐specific peptidase 9, X‐linked (USP9X). HDAC6 promotes GS deacetylation, while USP9X removes its K48‐linked polyubiquitination, enhancing GS stability.

Trimerization of 1,2‐Diaminocyclohexane Catalyzed by a Metal–Organic Cage Tandem Catalyst with Dual Biomimetic Active Sites

Advanced Science, EarlyView.
Dual biomimetic active sites, i.e., mononuclear {ZnII(L)(H2O)} and dinuclear {L2ZnII(CHO2)(OH)ZnIIL2}, have been successfully intergrated into a metal–organic cage, Zn20‐MOC. These two different active sites in Zn20‐MOC catalyze different steps of cascade trimerization of 1,2‐diaminocyclohexane. The mononuclear {ZnII(L)(H2O)} site catalyzes the initial

A Universal Approach to Anchoring Chromophores onto Magnetic Scaffold for Achieving Easily Recyclable Heterogeneous Photocatalytic Systems

Advanced Science, EarlyView.
The practical application of chromophores such as porphyrins, coumarins, anthraquinones, and pyrene derivatives in photocatalysis is severely limited by catalyst stability and reusability. In this work, a simple and universal strategy is presented for preparing highly efficient and recyclable heterogeneous photocatalysts for the oxidative coupling of ...
