Molecular cloning of a novel glucuronokinase/putative pyrophosphorylase from zebrafish acting in an UDP-glucuronic acid salvage pathway.

PLoS ONE, 2014
In animals, the main precursor for glycosaminoglycan and furthermore proteoglycan biosynthesis, like hyaluronic acid, is UDP-glucuronic acid, which is synthesized via the nucleotide sugar oxidation pathway.

Measuring catalytic mechanism similarity – a new approach to study enzyme function and evolution

The FEBS Journal, EarlyView.
We introduce a previously undescribed computational method to measure the similarity of enzyme mechanisms, enabling comparison of catalytic steps across hundreds of enzymes. Applying this method to a database of enzyme mechanisms demonstrated its ability to automatically uncover functional and evolutionary relationships, independently of sequence and ...

Evaluation of NAD(+)-dependent DNA ligase of mycobacteria as a potential target for antibiotics [PDF]

, 2007
Mycobacteria contain genes for several DNA ligases, including ligA, which encodes a NAD+-dependent enzyme that has been postulated to be a target for novel antibacterial compounds.

TENT5C functions as a corepressor in the ligand‐bound glucocorticoid receptor and estrogen receptor α complexes

The FEBS Journal, EarlyView.
TENT5C is a suppressor of ERα and GR transcriptional activation. A specific LXXLL motif in TENT5C, absent in the other members of the TENT5 subfamily, mediates a stable interaction with the Ligand Binding Domain of ERα but not with that of GR.

Probing carbohydrate biocatalysis through the use of electrospray ionization mass spectrometry and isothermal titration calorimetry [PDF]

, 2005
Electrospray ionization mass spectrometry,(ESI-MS)-based assays have been newly developed to study three classes of enzymes (sugar nucleotidyltransferases, glycosyltransferases, and phosphorylases) from the three distinct families of life: archaea ...

Thermodynamics of binding of divalent magnesium and manganese to uridine phosphates: implications for diabetes-related hypomagnesaemia and carbohydrate biocatalysis

Chemistry Central Journal, 2008
Background Although the necessity of divalent magnesium and manganese for full activity of sugar nucleotidyltransferases and glycosyltransferases is well known, the role of these metal cations in binding the substrates (uridine 5'-triphosphate, glucose-1-

Multi‐Omic Analysis of Glutamate Excitotoxicity in Primary Neuronal Cultures

Journal of Neurochemistry, Volume 169, Issue 6, June 2025.
Our study on rat neuron cells found 250 μM glutamate to be toxic, causing neuron death. We identified genes in pathways linked to apoptosis, neuron plasticity, and cell signaling, along with proteins regulating the cell cycle and tumor proliferation.

Polymorphic toxin systems: Comprehensive characterization of trafficking modes, processing, mechanisms of action, immunity and ecology using comparative genomics

Biology Direct, 2012
Background Proteinaceous toxins are observed across all levels of inter-organismal and intra-genomic conflicts. These include recently discovered prokaryotic polymorphic toxin systems implicated in intra-specific conflicts.

cGAS/STING‐Independent Induction of Type I Interferon by Inhibitors of the Histone Methylase KDM5B

The FASEB Journal, Volume 39, Issue 9, 15 May 2025.
Mechanism of HEXIM1 regulation of Type I Interferon. ABSTRACT Studies support the role of hexamethylene bis‐acetamide [HMBA] induced protein 1 (HEXIM1) as a tumor suppressor. We previously reported that the histone demethylase, KDM5B, inhibits the expression of HEXIM1, and KDM5B inhibitors (KDM5Bi) upregulate HEXIM1 expression. As a consequence, KDM5Bi
