New Advances in the Exploration of Esterases with PET and Fluorescent Probes

open access: yesMolecules, 2023
Esterases are hydrolases that catalyze the hydrolysis of esters into the corresponding acids and alcohols. The development of fluorescent probes for detecting esterases is of great importance due to their wide spectrum of biological and industrial ...

Understanding the structural and functional properties of carbohydrate esterases with a special focus on hemicellulose deacetylating acetyl xylan esterases

open access: yesMycology, 2018
Acetyl and methyl esterifications are two major naturally found substitutions in the plant cell-wall polysaccharides. The non-cellulosic plant cell-wall polysaccharides such as pectin and hemicellulose are differentially esterified by the O-acetyl and ...

Structural diversity of carbohydrate esterases

open access: yes, 2017
Carbohydrate esterases (CEs) catalyze the de-O or de-N-acylation by removing the ester decorations from carbohydrates. CEs are currently classified in 15 families in the Carbohydrate-Active Enzyme (CAZy) database, which classifies a large variety of ...
