Cryo‐EM structure of GH43 β‐Xylosidase from Enterobacter cloacae provides insights into substrate specificity and the role of an auxiliary domain in enzymatic activity

The FEBS Journal, EarlyView.
Xylan, the second most abundant plant cell wall polysaccharide, is degraded by β‐xylanases and β‐xylosidases. Here, we present the 2.65 Å cryo‐EM structure of Enterobacter cloacae β‐xylosidase (EcXyl43, GH43) and the 2.4 Å X‐ray structure of its inactive F507A mutant.

OVEREXPRESSION OF SIALIDASE (NEU1) PROMOTES INTERLEUKIN-6 INDUCED INFLAMMATION IN HUMAN NEUROGLIA AND MONOCYTIC THP-1 CELLS [PDF]

, 2006
Mammalian sialidases are hydrolytic enzymes that initiate the removal of terminal a2-3, a2-6 and a2-8 sialic acid residues from various sialylated glycoconjugates.

Glucose Catabolite Repression Participates in the Regulation of Sialidase Biosynthesis by Antarctic Strain Penicillium griseofulvum P29

Journal of Fungi
Sialidases (neuraminidases) catalyze the removal of terminal sialic acid residues from glycoproteins. Novel enzymes from non-clinical isolates are of increasing interest regarding their application in the food and pharmaceutical industry.

A posttranslational proteomic survey of a single anatomically preserved human 20‐week postconception brain

Journal of Anatomy, EarlyView.
A well‐preserved 20 post‐conception week human brain was obtained and finely dissected into 18 anatomically distinct regions, including the pia mater. Each region underwent in‐depth proteomic analysis, encompassing both total protein content and post‐translational modifications.

Discrimination of Gardnerella Species by Combining MALDI-TOF Protein Profile, Chaperonin cpn60 Sequences, and Phenotypic Characteristics

Pathogens, 2021
The description of Gardnerella vaginalis was recently updated and three new species, including nine genome species within Gardnerella, were defined using whole genome sequences and matrix assisted laser desorption ionization time of flight (MALDI-TOF ...

Effects of Diaceto-Dipropyl-Disulphide on Plasma Sialic Acid and Renal Tissue Thiol Levels in Alloxan Diabetic Rats [PDF]

Journal of Clinical and Diagnostic Research, 2016
Introduction: Plasma sialic acid levels are elevated in Diabetes Mellitus (DM) patients with proteinuria. Renal damage is mainly caused by free radicals that are excessively generated in DM. Thiols play an important role in the cellular antioxidative

Functional validation of a modified platelet desialylation test for immune and hereditary thrombocytopenias

Transfusion Medicine, EarlyView.
Abstract Background Thrombocytopenia arises from heterogeneous inherited and acquired disorders, and identifying the underlying platelet clearance mechanisms remains challenging. Platelet desialylation, characterised by loss of sialic acid and consequent exposure of terminal β‐galactose residues recognised by the Ashwell–Morell receptor, represents an ...

Sialidase inhibitors attenuate pulmonary fibrosis in a mouse model

Scientific Reports, 2017
Fibrosis involves increasing amounts of scar tissue appearing in a tissue, but what drives this is unclear. In fibrotic lesions in human and mouse lungs, we found extensive desialylation of glycoconjugates, and upregulation of sialidases.
