Mechanistic insights into HapC: A key enzyme in prodiginine biosynthesis in Hahella chejuensis

The FEBS Journal, EarlyView.
HapC catalyzes prodiginine biosynthesis through coordinated movements of its ATP‐binding, substrate‐binding, and catalytic‐swivel domains. The enzyme shows tolerance toward short‐chain MAP analogs, and docking analyses reveal key residues and structural features underlying its substrate flexibility.

1H NMR metabolomics and lipidomics analysis of neutrophils reveals biomarkers of ageing, inflammageing and frailty

The FEBS Journal, EarlyView.
Using 1H NMR metabolomics, we measured polar and lipid metabolites from human blood neutrophils from people with frailty (n = 31, mean age 84Y), people with rheumatoid arthritis (n = 16, mean age 55Y), robust older (n = 24, mean age 66Y) and healthy younger people (n = 21, mean age 22Y).

Mitochondrial transfer in acute myeloid leukaemia and multiple myeloma: Mechanisms, consequences and potential therapeutic opportunities

The FEBS Journal, EarlyView.
Mitochondria can be transferred from bone marrow cells to cancer cells in acute myeloid leukaemia and multiple myeloma, boosting tumour energy production, growth, and drug resistance. This review highlights key transfer mechanisms and shows how targeting mitochondrial movement and dynamics may offer new therapeutic strategies to limit cancer ...

Toward understanding the catalytic mechanism for two classes of bacterial phospholipid N‐methyltransferases

The FEBS Journal, EarlyView.
Phospholipid N‐methyltransferases (Pmts) synthesize phosphatidylcholine in many bacteria. In this study, we compared the catalytic mechanisms of two bacterial Pmt classes: the Rhodobacter (R‐) and the Sinorhizobium (S‐) type. Representative enzymes for each class were derived from Rubellimicrobium thermophilum and Agrobacterium tumefaciens ...

Characterization of Current Base Editors Towards Rational Development of Novel Genome Editing Tools

Base editors are a new family of programmable genome editing tools capable of introducing highly efficient single base changes. These fusion enzymes take advantage of CRISPR-Cas gRNA technology to access genomic targets of interest but use tethered ...

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.

Physiological media and oxygen levels modulate cancer hallmarks in cultured breast cancer cells

The FEBS Journal, EarlyView.
MCF7 breast cancer cells were cultured in standard conditions (18% O2 and DMEM) and physiological conditions (5% O2 and Plasmax, a medium modeled after the human plasma metabolome). A combined transcriptomic and proteomic approach was used to identify gene expression signatures at the mRNA and protein levels upstream of functional enrichment analyses ...

Gene Editing for Haemophilia—The Next Frontier

Haemophilia, EarlyView.
ABSTRACT The recently approved haemophilia A and B gene therapies via adeno‐associated virus (AAV) showed a promising therapeutic response after a single injection, but there are still limitations, including the potential loss of transgene expression and restriction in adults.

Emerging experimental and bioinformatic approaches in RNA interference‐based pest control research

Insect Molecular Biology, EarlyView.
Double‐stranded RNA (dsRNA) visualization, RNA‐induced silencing complex (RISC)‐bound sRNA‐seq and RNA degradomics allow investigating dsRNA uptake and processing, guide small interfering RNA selection and RISC‐mediated target mRNA cleavages. Transcriptomic and proteomic profiles of genome‐wide responses to dsRNA, including off‐target and compensatory ...

Transcriptomic and proteomic signatures underlying nymphal adaptation and foam production in the forage pest Mahanarva spectabilis

Insect Molecular Biology, EarlyView.
RNA‐seq and Batelli gland proteomics of fifth‐instar Mahanarva spectabilis nymphs reveal transcripts and proteins associated with xylem feeding, foam production and environmental interaction. Functional annotation identified genes involved in osmoregulation, detoxification, chemosensation and stress responses, while proteomic analysis confirmed ...
