The paper identifies three new glycoside hydrolase families of β-1,2-glucanases and reveals their functional and structural relationships within a superfamily.

The paper identifies and characterizes α-1,6-cyclized β-1,2-glucan synthases, revealing their role in plant-pathogen interactions and potential applications in agriculture.

This study identifies a beta-galactosidase from Bacteroides xylanisolvens that hydrolyzes beta-1,2-galactooligosaccharides, revealing its unique substrate specificity through structural and biochemical analysis.

This study identifies OpgD as the enzyme responsible for synthesizing CβG16, a key virulence factor in Xanthomonas, revealing a novel transglycosylation mechanism with implications for developing new agrichemicals.

The paper functionally and structurally analyzes the cyclization domain of a cyclic β-1,2-glucan synthase, revealing it produces cyclic β-1,2-glucans through transglycosylation without hydrolysis and proposes it belongs to a new glycoside hydrolase family.
