Hooked on α-d-galactosidases: from biomedicine to enzymatic synthesis

Critical Reviews in Biotechnology, 2016
α-d-Galactosidases (EC 3.2.1.22) are enzymes employed in a number of useful bio-based applications. We have depicted a comprehensive general survey of α-d-galactosidases from different origin with special emphasis on marine example(s).

GDP‐fucose transporter SLC35C1: a potential regulatory role in cytosolic GDP‐fucose and fucosylated glycan synthesis

FEBS Open Bio, EarlyView.
The inactivation of SLC35C1 (GDP‐fucose transporter) and enzymes involved in GDP‐fucose biosynthesis was studied. Fucose supplementation increases the level of GDP‐fucose to abnormal, millimolar values in the absence of the TSTA3 protein and SLC35C1 in contrast to the GMDS/SLC35C1 double mutant.

Research Progess in the Evolution and Functions of Plant α-galactosidases

Guangdong nongye kexue, 2022
α-galactosidase (α-gal, EC 3.2.1.22) is a kind of exoglycosidase that can specifically catalyze the hydrolysis ofα-galactoside bonds. It has the ability to hydrolyze theα-1, 6-galactoside bonds involved in galacto-oligosaccharides such as melibiose ...
