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

open access: yesThe 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.

Structural insights into tyrosine sulfation of CCR5 by human tyrosylprotein sulfotransferase‐1

open access: yesThe FEBS Journal, EarlyView.
Structural analysis of human tyrosylprotein sulfotransferase‐1 (hTPST1) bound to a CCR5 N‐terminal peptide reveals how hTPST1 recognizes the Tyr3 sulfation site. Structure‐guided models of additional CCR5 sulfation states and full‐length assemblies provide a framework for understanding CCR5 tyrosine sulfation, a post‐translational modification relevant

Defining the role of αC helix interactions in the activation of the integrin αI domain

open access: yesThe FEBS Journal, EarlyView.
The α2I domain of the α2β1 integrin contains a distinctive αC helix and a conserved Arg288‐Glu318 ion pair that stabilizes the closed state of the domain. Disruption of this ion pair in the activated α2I variant unwinds the αC helix, which allows interaction with additional collagen‐binding sites increasing collagen binding.

Insights into tandem dioxygenases—copper radical oxidases in fungal Phytopathogens of the Colletotrichum acutatum species complex

open access: yesThe FEBS Journal, EarlyView.
In Colletotrichum acutatum species complex, conserved ring‐cleavage dioxygenases located adjacent to AA5_2 enzymes were investigated as potential redox partners. Biochemical analyses identified the dioxygenases as intradiol‐cleaving enzymes preferentially oxidizing methyl‐substituted catechols, while AA5_2 enzymes displayed weak alcohol oxidase ...

Genome assembly of Elcysma westwoodi provides insights into host‐plant cyanogenic glucoside detoxification and chemical defence gene evolution

open access: yesInsect Molecular Biology, EarlyView.
A chromosome‐level genome of Elcysma westwoodi was assembled. The genome encodes 272 detoxification‐related genes. A single‐copy bCAS was retained for cyanide detoxification. CYP405A and CYP332A were recruited into cyanogenic defence evolution. UGT33A retained a conserved GT‐B fold and catalytic domains.

Improving Decision‐Making in the Identification of Tephritidae Larvae at Import in the European Union and Key to Third Instar Larvae

open access: yesJournal of Applied Entomology, EarlyView.
ABSTRACT The Tephritidae family, or true fruit flies, comprises approximately 250 species recognized as economically significant due to their capacity to infest commercial fruits. These pests pose serious threats to both food security and trade, and are considered quarantine pests in areas where they are not yet established. In the European Union (EU),
