Limited Hydrolysis of Polysialic Acid by Human Neuraminidase Enzymes

, 2021
Regulation of sialic acids by human neuraminidase (hNEU) enzymes is important to many biological processes. Defining hNEU substrate tolerance can help to elucidate the roles of these enzymes in regulating sialosides in human health and disease ...

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 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 ...

Microwave-mediated analysis for sugar, fatty acid, and sphingoid compositions of glycosphingolipids

Journal of Lipid Research, 2004
For chemical characterization of glycosphingolipids, it is necessary to determine the chemical compositions of three constituents, i.e., sugars, fatty acids, and sphingoids.

Acid Hydrolysis of Urinary Estriol

Clinical Chemistry, 1967
Abstract One hundred and twenty determinations of urinary estriol were carried out following acid hydrolysis and gas liquid chromatography. Through the use of a radioactive standard, it was shown that, with an increase in specific gravity (1.001 to 1.025), a steady linear decline of estriol recovery occurred (93% to 56%). The presence of

Cell geometry and membrane protein crowding constrain Escherichia coli growth rate, overflow metabolism, respiration, and maintenance energy

FEBS Letters, EarlyView.
The physical dimensions and shape of bacterial cells define the surface area available to acquire nutrients and the volume available for synthesizing proteins and DNA. Here, we use computational systems biology to decode the importance of cell geometry as a major determinant of prokaryotic phenotype, including growth rate and metabolic efficiency. This

A solid state fungal fermentation-based strategy for the hydrolysis of wheat straw

, 2013
This paper reports a solid-state fungal fermentation-based pre-treatment strategy to convert wheat straw into a fermentable hydrolysate. Aspergillus niger was firstly cultured on wheat straw for production of cellulolytic enzymes and then the wheat straw
