Environmental and Gut Bacteroidetes: The Food Connection
Members of the diverse bacterial phylum Bacteroidetes have colonized virtually all types of habitats on Earth. They are among the major members of the microbiota of animals, especially in theExpand

Transfer of carbohydrate-active enzymes from marine bacteria to Japanese gut microbiota
Gut microbes supply the human body with energy from dietary polysaccharides through carbohydrate active enzymes, or CAZymes, which are absent in the human genome. These enzymes target polysaccharidesExpand

Structural Evidence for the Evolution of Xyloglucanase Activity from Xyloglucan Endo-Transglycosylases: Biological Implications for Cell Wall Metabolism[W]
High-resolution, three-dimensional structures of the archetypal glycoside hydrolase family 16 (GH16) endo-xyloglucanases Tm-NXG1 and Tm-NXG2 from nasturtium (Tropaeolum majus) have been solved byExpand

The endo-beta-agarases AgaA and AgaB from the marine bacterium Zobellia galactanivorans: two paralogue enzymes with different molecular organizations and catalytic behaviours.
Two beta-agarase genes, agaA and agaB, were functionally cloned from the marine bacterium Zobellia galactanivorans. The agaA and agaB genes encode proteins of 539 and 353 amino acids respectively,Expand

Bioconversion of red seaweed galactans: a focus on bacterial agarases and carrageenases
Agars and carrageenans are 1,3-α-1,4-β-galactans from the cell walls of red algae, substituted by zero (agarose), one (κ-), two (ι-), or three (λ-carrageenan) sulfate groups per disaccharidicExpand

Comparative Characterization of Two Marine Alginate Lyases from Zobellia galactanivorans Reveals Distinct Modes of Action and Exquisite Adaptation to Their Natural Substrate*
Background: Alginolytic systems from marine bacteria are crucial for algal biomass conversion, yet their molecular mechanisms remain poorly understood. Results: Structural and biochemicalExpand

The Three-dimensional Structures of Two β-Agarases*
Agars are important gelifying agents for biochemical use and the food industry. To cleave the β-1,4-linkages between β-d-galactose and α-l-3,6-anhydro-galactose residues in the red algal galactansExpand

The mechanism of substrate (aglycone) specificity in beta -glucosidases is revealed by crystal structures of mutant maize beta -glucosidase-DIMBOA, -DIMBOAGlc, and -dhurrin complexes.
The mechanism and the site of substrate (i.e., aglycone) recognition and specificity were investigated in maize beta-glucosidase (Glu1) by x-ray crystallography by using crystals of a catalyticallyExpand

Genome structure and metabolic features in the red seaweed Chondrus crispus shed light on evolution of the Archaeplastida
Red seaweeds are key components of coastal ecosystems and are economically important as food and as a source of gelling agents, but their genes and genomes have received little attention. Here weExpand

Atomic resolution (1.0 A) crystal structure of Fusarium solani cutinase: stereochemical analysis.
X-ray data have been recorded to 1.0 A resolution from a crystal of Fusarium solani cutinase using synchrotron radiation and an imaging-plate scanner. The anisotropic treatment of thermal motion ledExpand
