Crystal Structure of Thermotoga maritima α-Glucosidase AglA Defines a New Clan of NAD+-dependent Glycosidases [PDF]
Glycoside hydrolase family 4 represents an unusual group of glucosidases with a requirement for NAD(+), divalent metal cations, and reducing conditions. The family is also unique in its inclusion of both alpha- and beta-specific enzymes.

β-xylosidases (4-β-d-xylan xylohydrolase, E.C. 3.2.1.37) are glycoside hydrolases (GH) catalyzing the hydrolysis of (1→4)-β-d-xylans, allowing for the removal of β-d-xylose residues from its non-reducing termini.

Identification of Carbohydrate Metabolism Genes in the Metagenome of a Marine Biofilm Community Shown to Be Dominated by Gammaproteobacteria and Bacteroidetes [PDF]
Polysaccharides are an important source of organic carbon in the marine environment and degradation of the insoluble and globally abundant cellulose is a major component of the marine carbon cycle.

Background: Lignocellulose is considered a renewable organic material, but the industrial production of biofuel from lignocellulose is challenging because of the lack of highly active hydrolytic enzymes.

First crenarchaeal chitinase found in Sulfolobus tokodaii [PDF]
This is the first description of a functional chitinase gene within the crenarchaeotes. Here we report of the heterologues expression of the ORF BAB65950 from Sulfolobus tokodaii in E. coli.

Glycoside Hydrolases across Environmental Microbial Communities [PDF]
Across many environments microbial glycoside hydrolases support the enzymatic processing of carbohydrates, a critical function in many ecosystems. Little is known about how the microbial composition of a community and the potential for carbohydrate processing relate to each other.

Induction and Characterisation of Lignocellulolytic Activities from Novel Deep-Sea Fungal Secretomes
Fungi are increasingly recognised as being able to inhabit extreme environments. The deep sea is considered an extreme environment because of its low temperatures, high hydrostatic and lithostatic pressures, 3.5% salinity, and low oxygen, nutrient and ...

How a Glycoside Hydrolase Recognizes a Helical Polyglucan [PDF]
Similarly to other biopolymers, linear polysaccharides can form double- or triple-helical structures. How enzymes recognize and manage this quaternary structure is an unresolved question. In this issue of Structure, Pluvinage et al. (2017) shed light on the structural complementarity between family GH81 glycoside hydrolase and the quaternary structure ...

Structure and stereochemistry of the base excision repair glycosylase MutY reveal a mechanism similar to retaining glycosidases. [PDF]
MutY adenine glycosylases prevent DNA mutations by excising adenine from promutagenic 8-oxo-7,8-dihydroguanine (OG):A mismatches. Here, we describe structural features of the MutY active site bound to an azaribose transition state analog which indicate a

A subfamily roadmap of the evolutionarily diverse glycoside hydrolase family 16 (GH16)
Glycoside hydrolase family (GH) 16 comprises a large and taxonomically diverse family of glycosidases and transglycosidases that adopt a common β-jelly-roll fold and are active on a range of terrestrial and marine polysaccharides.
