Structural and Functional Characterization of Drosophila melanogaster α-Amylase

Molecules, 2023
Insects rely on carbohydrates such as starch and glycogen as an energy supply for growth of larvae and for longevity. In this sense α-amylases have essential roles under extreme conditions, e.g., during nutritional or temperature stress, thereby ...

Targeting N-Terminal Human Maltase-Glucoamylase to Unravel Possible Inhibitors Using Molecular Docking, Molecular Dynamics Simulations, and Adaptive Steered Molecular Dynamics Simulations

Frontiers in Chemistry, 2021
There are multiple drugs for the treatment of type 2 diabetes, including traditional sulfonylureas biguanides, glinides, thiazolidinediones, α-glucosidase inhibitors, glucagon-like peptide-1 (GLP-1) receptor agonists, dipeptidyl peptidase IV (DPP-4 ...

Exploration of the Transglycosylation Activity of Barley Limit Dextrinase for Production of Novel Glycoconjugates

Molecules, 2023
A few α-glucan debranching enzymes (DBEs) of the large glycoside hydrolase family 13 (GH13), also known as the α-amylase family, have been shown to catalyze transglycosylation as well as hydrolysis. However, little is known about their acceptor and donor

Design of Novel Benzimidazole Derivatives as Potential α-amylase Inhibitors by 3D-QSAR Modeling and Molecular Docking Studies

Journal of the Turkish Chemical Society, Section A: Chemistry, 2020
The α-amylase is an enzyme of a highly conserved glycoside hydrolase family, α-amylase inhibitors can be used as clinical agents for the treatment of Diabetes Mellitus (DM). A 3D-QSAR study was performed on 45 2-aryl benzimidazole derivatives, which have

Structure and stereochemistry of the base excision repair glycosylase MutY reveal a mechanism similar to retaining glycosidases. [PDF]

, 2015
MutY adenine glycosylases prevent DNA mutations by excising adenine from promutagenic 8-oxo-7,8-dihydroguanine (OG):A mismatches. Here, we describe structural features of the MutY active site bound to an azaribose transition state analog which indicate a

Characterization of glycoside hydrolase family 11 xylanase from Streptomyces sp. strain J103; its synergetic effect with acetyl xylan esterase and enhancement of enzymatic hydrolysis of lignocellulosic biomass

Microbial Cell Factories, 2021
Background Xylanase-containing enzyme cocktails are used on an industrial scale to convert xylan into value-added products, as they hydrolyse the β-1,4-glycosidic linkages between xylopyranosyl residues.

Fully Deacetylated Chitooligosaccharides Act as Efficient Glycoside Hydrolase Family 18 Chitinase Inhibitors [PDF]

Journal of Biological Chemistry, 2014
Small molecule inhibitors against chitinases have potential applications as pesticides, fungicides, and antiasthmatics. Here, we report that a series of fully deacetylated chitooligosaccharides (GlcN)2-7 can act as inhibitors against the insect chitinase OfChtI, the human chitinase HsCht, and the bacterial chitinases SmChiA and SmChiB with IC50 values ...

Crystal structure-guided design of berberine-based novel chitinase inhibitors

Journal of Enzyme Inhibition and Medicinal Chemistry, 2020
Glycoside hydrolase family 18 (GH18) chitinases play an important role in various organisms ranging from bacteria to mammals. Chitinase inhibitors have potential applications as pesticides, fungicides, and anti-asthmatics.

A unique self-truncation of bacterial GH5 endoglucanases leads to enhanced activity and thermostability

BMC Biology, 2022
Background β-1,4-endoglucanase (EG) is one of the three types of cellulases used in cellulose saccharification during lignocellulosic biofuel/biomaterial production. GsCelA is an EG secreted by the thermophilic bacterium Geobacillus sp.

My Times with Professor Igor Kregar and some Hydrolytic Enzymes

Acta Chimica Slovenica, 2019
The late Professor Igor Kregar and this author had several overlapping biochemical research interests. One focus was the glycoside hydrolase, lysozyme, and the other was proteolytic enzymes and their inhibitors, in particular those present in tissues ...
