Phycocyanobilin biosynthesis in Galdieria sulphuraria requires isomerization of phycoerythrobilin synthesized by bilin reductases

open access: yesThe FEBS Journal, EarlyView.
The biosynthesis of bilins, tetrapyrroles essential for light harvesting and sensing, is performed by specific enzymes (FDBRs). In Galdieria sulphuraria, both phycobiliprotein types bind phycocyanobilin, despite lacking the canonical synthesizing gene PCYA. Instead, PEBA and PEBB are encoded, producing phycoerythrobilin, proposed to be later isomerized

ER proteostasis meets mitochondrial function: contact sites as hubs of communication and therapeutic targets

open access: yesThe FEBS Journal, EarlyView.
Proteostasis ensures proper protein folding, modification, and degradation, while its impairment triggers ER stress. Chronic ER stress and maladaptive UPR via the CHOP–ERO1 axis remodel ERMCs, altering calcium signaling and mitochondrial metabolism.

Bacterial Chaperone Domain Insertions Convert Human FKBP12 into an Excellent Protein-Folding Catalyst—A Structural and Functional Analysis

open access: yesMolecules
Many folding enzymes use separate domains for the binding of substrate proteins and for the catalysis of slow folding reactions such as prolyl isomerization. FKBP12 is a small prolyl isomerase without a chaperone domain.

Prompting Fab Yeast Surface Display Efficiency by ER Retention and Molecular Chaperon Co-expression. [PDF]

open access: yes, 2019
For antibody discovery and engineering, yeast surface display (YSD) of antigen-binding fragments (Fabs) and coupled fluorescence activated cell sorting (FACS) provide intact paratopic conformations and quantitative analysis at the monoclonal level, and ...

The competitive interplay of 12‐oxophytodienoic acid (OPDA), protein thiols, and glutathione

open access: yesThe FEBS Journal, EarlyView.
12‐Oxophytodienoic acid (OPDA) is a phytohormone involved in plant growth and stress defense. Due to its cyclopentenone moiety, OPDA can form Michael adducts with thiol‐containing compounds such as glutathione and cysteine residues of proteins, resulting in alterations of the cellular redox regulatory network.

Understanding how enzymes work: the journey to ensemble–function studies

open access: yesThe FEBS Journal, EarlyView.
For decades, structure–function has dominated biochemistry. Structures are highly valuable, yet more is needed to achieve a quantitative understanding of biomolecular function, because function emerges from an ensemble of states, rather than a static structure. We describe an ensemble–function framework applied to quantitatively dissect serine protease

Current perspectives on KMT2A fusion proteins and menin inhibition in paediatric acute myeloid leukaemia

open access: yesThe FEBS Journal, EarlyView.
Genetic rearrangements resulting in the expression of KMT2A fusion alleles can lead to dramatic transcriptional disturbances that contribute to the onset of acute leukaemias. Fortunately, menin inhibition has emerged as a promising new class of targeted therapy.

Development of PCR, LAMP and HRM‐Based Molecular Species Diagnostic Tools for Identifying Four Agricultural Pests in the Genus Helicoverpa (Lepidoptera: Noctuidae)

open access: yesJournal of Applied Entomology, EarlyView.
ABSTRACT Within the subfamily Heliothinae, the genus Helicoverpa comprises several highly destructive agricultural pests, including H. armigera, H. assulta, H. punctigera and H. zea. These species cause significant global crop losses due to their wide host range, long‐distance migratory behaviour, and potential for interspecific hybridization.
