Microarrayed Allergen Molecules Distinguish IgE Sensitisation to Blomia tropicalis and Dermatophagoides pteronyssinus

open access: yesAllergy, EarlyView.
This study established a microarray containing a representative panel of purified Blo t and Der p allergens for the identification of patients sensitised to Blo t and/or Der p. Results indicate that the microarray based on Blo t and Der p allergens is a useful tool for the identification of Blo t‐ and/or Der p‐sensitised patients. The microarray may be

A new branch of mammalian vitamin B6 metabolism: AKR1C‐mediated conversion of pyridoxal to pyridoxine and 4‐pyridoxolactone

open access: yesThe FEBS Journal, EarlyView.
Pyridoxal 5′‐phosphate (PLP) homeostasis relies on salvage enzymes, yet key metabolic branches remain undefined. We identify AKR1C isozymes as previously undescribed contributors that convert pyridoxal into pyridoxine or 4‐pyridoxolactone through reductase and dehydrogenase activities.

KU80 suppresses endonuclease G activity to preserve genomic integrity

open access: yesThe FEBS Journal, EarlyView.
Under normal conditions, EndoG remains restricted to mitochondria and the genome remains intact. When KU80 is absent, EndoG translocates into the nucleus, where it promotes DNA fragmentation and genomic instability. Thus, this work highlights the importance of KU80 in tightly controlling EndoG localization to preserve genome stability.

Tyrosine residues at the substrate binding site in human NQO1 homodimer: Protein conformational dynamics and optimization of substrate binding geometry

open access: yesThe FEBS Journal, EarlyView.
Human NAD(P)H:quinone oxidoreductase 1 is a homodimeric flavoenzyme crucial for redox metabolism and linked to significant health issues. Point mutations at Tyr126 and Tyr128 demonstrate their essential roles in optimizing substrate binding geometry for catalysis, as well as in half‐site reactivity and conformational dynamics during the enzyme's ...

S‐Adenosylmethionine (SAM) hydrolases counter increased SAM epimerisation in thermophilic archaea

open access: yesThe FEBS Journal, EarlyView.
S‐Adenosyl‐l‐methionine (SAM) is a vital enzyme cofactor. Epimerisation at the sulfonium centre of biologically active (SS,SCα)‐SAM is driven by heat, yielding biologically inactive (RS,SCα)‐SAM. Here, two novel archaeal SAM hydrolases from the thermophilic Sulfolobus acidocaldarius and the halophilic Haloferax volcanii are shown to cleave (RS,SCα)‐SAM.

Discovery of a cryptic aminoacidic triad involved in the temperature adaptation of GH1 enzymes

open access: yesThe FEBS Journal, EarlyView.
Cold‐active enzymes retain high catalytic activity at low temperatures but are characterized by thermal instability, a behavior not fully understood. Comparison between a cold‐active GH1 and its mesophilic counterparts highlights the role of a three‐residue motif (W‐M‐F) in conferring structural stability to a mesophilic GH1.
