NMR Data Analysis of Acarbose

Chinese Journal of Magnetic Resonance
Acarbose, an α-glucosidase inhibitor, has been widely used in the treatment of type-II diabetes due to its unique mechanism of action. In this study, comprehensive and accurate 1H and 13C NMR data of acarbose in DMSO-d6, including 1H NMR data of all ...

Pseudopterosins and -Pseudopterosins: Compilation and Revision of Conflicting NMR Data, Names, Numbering Systems and Structural Elucidation

Natural Product Communications, 2022
The present review is focussed on the structural elucidation of the bicyclic and tricyclic diterpenoid title compounds isolated from Pseudopterogorgia species, displaying a direct structural relationship with the biosynthetic precursor GGPP (regular ...

Are feature assignment errors due to attraction? The case of Bulgarian numeral phrase

Frontiers in Psychology
Well-studied attraction errors in speakers' production of subject-verb agreement arise from featural similarity between the attractor and the target (e.

Spatiotemporal and quantitative analyses of phosphoinositides – fluorescent probe—and mass spectrometry‐based approaches

FEBS Letters, EarlyView.
Fluorescent probes allow dynamic visualization of phosphoinositides in living cells (left), whereas mass spectrometry provides high‐sensitivity, isomer‐resolved quantitation (right). Their synergistic use captures complementary aspects of lipid signaling. This review illustrates how these approaches reveal the spatiotemporal regulation and quantitative

Structural reform, revenue adequacy and optimal tax assignment in local government

Commonwealth Journal of Local Governance, 2009
A striking feature of local government reform in many Commonwealth countries has been a heavy reliance on structural reform, often in the form of forced local council amalgamation. This paper argues that the long-run success of structural change in local

Structural identification of N-glycan isomers using logically derived sequence tandem mass spectrometry

Communications Chemistry, 2021
Mass spectrometry can be used for structural determination of N-glycans, but commonly requires prior derivatisation or comparison to a library of standards.

Protein pyrophosphorylation by inositol pyrophosphates — detection, function, and regulation

FEBS Letters, EarlyView.
Protein pyrophosphorylation is an unusual signaling mechanism that was discovered two decades ago. It can be driven by inositol pyrophosphate messengers and influences various cellular processes. Herein, we summarize the research progress and challenges of this field, covering pathways found to be regulated by this posttranslational modification as ...

A Review on Eigenstructure Assignment Methods and Orthogonal Eigenstructure Control of Structural Vibrations

Shock and Vibration, 2009
This paper provides a state-of-the-art review of eigenstructure assignment methods for vibration cancellation. Eigenstructure assignment techniques have been widely used during the past three decades for vibration suppression in structures, especially in

Structural instability impairs function of the UDP‐xylose synthase 1 Ile181Asn variant associated with short‐stature genetic syndrome in humans

FEBS Letters, EarlyView.
The Ile181Asn variant of human UDP‐xylose synthase (hUXS1), associated with a short‐stature genetic syndrome, has previously been reported as inactive. Our findings demonstrate that Ile181Asn‐hUXS1 retains catalytic activity similar to the wild‐type but exhibits reduced stability, a looser oligomeric state, and an increased tendency to precipitate ...

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.
