Synthesis and structure-activity relationships of cerebroside analogues as substrates of cerebroside sulphotransferase and discovery of a competitive inhibitor

open access: yesJournal of Enzyme Inhibition and Medicinal Chemistry, 2020
Metachromatic leukodystrophy (MLD) is a rare genetic disease characterised by a dysfunction of the enzyme arylsulphatase A leading to the lysosomal accumulation of cerebroside sulphate (sulphatide) causing subsequent demyelination in patients. The enzyme

Development of an Enzyme-Based Thin-Layer Chromatographic Assay for the Detection of Cyclooxygenase-2 Inhibitors

open access: yesSeparations, 2022
The search for new anti-inflammatory drugs with less side effects requires simple, fast and reliable screening methods. In this context, we have developed a sensitive thin-layer chromatographic (TLC) assay on silica gel plates to detect cyclooxygenase-2 (

Cloning, expression, purification and assay of sorbitol dehydrogenase from "Feicheng" peach fruit (Prunus persica)

open access: yesBrazilian Archives of Biology and Technology, 2013
A gene encoding NAD+-dependent sorbitol dehydrogenase (SDH) in peach fruit was cloned and expressed in Escherichia coli. Recombinant SDH protein with 6×His-tagged was localized exclusively in the cytoplasmic soluble fraction of E.

A method for assaying deubiquitinating enzymes [PDF]

open access: yesBiological Procedures Online, 1998
A general method for the assay of deubiquitinating enzymes was described in detail using (125)I-labeled ubiquitin-fused alphaNH-MHISPPEPESEEEEEHYC (referred to as Ub-PESTc) as a substrate. Since the tyrosine residue in the PESTc portion of the fusion protein was almost exclusively radioiodinated under a mild labeling condition, such as using IODO-BEADS,
