Deciphering Branched Galactomannan Structures via Multistage Ion Mobility MS and MSn Fragmentation (Multistage IMSn)

Rapid Communications in Mass Spectrometry, EarlyView.
ABSTRACT Rationale Hemicelluloses are abundant carbohydrate components in plant cell walls. They play a crucial structural role in binding cellulose microfibrils, in addition to other biological functions. Their high structural variability directly influences their biological properties, making it important to establish a structure–function ...

Biochemical characterization of the xylan hydrolysis profile of the extracellular endo-xylanase from Geobacillus thermodenitrificans T12

BMC Biotechnology, 2017
Background Endo-xylanases are essential in degrading hemicellulose of various lignocellulosic substrates. Hemicellulose degradation by Geobacillus spp. is facilitated by the hemicellulose utilization (HUS) locus that is present in most strains belonging ...

Russian wheat aphid: a model for genomic plasticity and a challenge to breeders

Insect Science, EarlyView.
Invasive foundress finds suitable habitat and reproduces through pathogenesis. Wingless females produce life offspring quickly, which leads to high population densities. High population densities result in competition, which may induce epigenetic changes and wing development for dispersal.

Insights into Adsorption Characterization of Sulfated Xylans onto Poly(ethylene terephthalate)

, 2020
The main aim of this investigation was to study the interaction of sulfated xylans as antithrombotic substances with poly(ethylene terephthalate) (PET) model films as a model for blood contacting surfaces. The adsorption of sulfated xylans onto PET model

Comparison of action pattern of two xylanases from trichoderma reesei and two xylanases from aspergillus oryzae on different xylans

, 2000
Xylans are important components of plant cell walls. The main component in xylans is xylose, which forms the backbone (1,2). Arabinose and 4-O-methylglucuronic acid exist as side groups. In addition several xylans contain acetyl substituents. Some xylans

Structural and thermodynamic analyses of a novel β‐1,2‐glucan binding mode in the ABC transporter solute‐binding protein Chy400_4166 from Chloroflexus aurantiacus

The FEBS Journal, EarlyView.
Cyclic β‐1,2‐glucan (CβG)‐associated solute‐binding protein of type I ABC transporter was originally identified in Chloroflexus aurantiacus, a phototrophic bacterium. Crystal structures in complex with CβGs revealed unique binding modes that are fundamentally distinct from that of the short β‐1,2‐glucooligosaccharides‐binding protein.

Gorse (Ulex europaeus) as a possible source of xylans by hydrothermal treatment

, 2011
Autocatalytic hydrothermal process conditions were used to study Ulex europæus (Gorse) as a source of xylan compounds. The aim was to study the possibilities for using this unutilised biomass material to produce xylans.

Contrasted enzymatic cocktails reveal the importance of cellulases and hemicellulases activity ratios for the hydrolysis of cellulose in presence of xylans [PDF]

, 2016
International audienceVarious enzymatic cocktails were produced from two Trichoderma reesei strains, a cellulase hyperproducer strain and a strain with β-glucosidase activity overexpression. By using various carbon sources (lactose, glucose, xylose, hemi-

Cryo‐EM structure of GH43 β‐Xylosidase from Enterobacter cloacae provides insights into substrate specificity and the role of an auxiliary domain in enzymatic activity

The FEBS Journal, EarlyView.
Xylan, the second most abundant plant cell wall polysaccharide, is degraded by β‐xylanases and β‐xylosidases. Here, we present the 2.65 Å cryo‐EM structure of Enterobacter cloacae β‐xylosidase (EcXyl43, GH43) and the 2.4 Å X‐ray structure of its inactive F507A mutant.
