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.

Functional characterization of 42 CK2α de novo variants associated with Okur‐Chung neurodevelopmental syndrome

The FEBS Journal, EarlyView.
Okur‐Chung neurodevelopmental syndrome (OCNDS) is a neurodevelopmental disorder associated with mutations in the gene coding for Protein kinase CK2α. In this work, 42 variants of CK2α associated with OCNDS were characterized in vitro. This included determination of catalytic activity and CK2α/CK2β‐interaction as well as an assessment of evolutionary ...

A distinct gene expression mechanism for d‐amino acid utilization in hyperthermophilic archaeon Pyrococcus horikoshii

The FEBS Journal, EarlyView.
The genes PH0137, PH0138, and PH0140 form a cluster in the genome of Pyrococcus horikoshii. The PH0140 gene encodes a transcription factor identified as a d‐amino acid‐responsive regulatory protein (DARP). In feast mode, l‐Ile‐bound DARP binds to the promoter and represses transcription of PH0137 and PH0138. In famine mode, DARP binds to d‐allo‐Ile and

PEG400 regulates Falcipain 2 activity through an allosteric mechanism

The FEBS Journal, EarlyView.
Falcipain‐2 can potentially be leveraged as a drug target due to its critical role as a haemoglobinase during the intra‐erythrocytic stage of Plasmodium falciparum. Here, we investigate the regulation of the proteolytic and haemoglobinase activity of falcipain‐2 in the presence of polyethylene glycol.

The tryptophan prenyltransferase ComQ from Bacillus subtilis 168 can prenylate daptomycin at Trp1

The FEBS Journal, EarlyView.
ComQ168 from Bacillus subtilis 168 catalyzes C‐terminal tryptophan farnesylation of ComX to generate a competence‐inducing pheromone. Recombinant ComQ168 also modifies cyclic peptides, including Daptomycin, likely at the N‐terminal tryptophan. Structural modeling highlights a C‐terminal binding region, supporting substrate promiscuity and establishing ...

Efficacy Assessment of Montanide GEL 02 PR and Liposome‐Based Encapsulation as Adjuvants for an FrpA Subunit Vaccine Against Photobacteriosis in Solea senegalensis

Journal of Fish Diseases, EarlyView.
ABSTRACT Photobacteriosis is a major threat to marine aquaculture, and the siderophore transporter FrpA represents a promising target for effective subunit vaccine development. In this study, we evaluated Montanide GEL 02 PR and phosphatidylcholine‐based liposomes as aqueous and safer alternatives to Freund's adjuvant for an FrpA‐based subunit vaccine ...

The GmGT‐2F, a trihelix transcription factor, regulates seed oil content by directly activating GmAGAL transcription in soybean

Journal of Integrative Plant Biology, EarlyView.
In soybean, the trihelix transcription factor GmGT‐2F positively regulates the expression of the α‐galactosidase gene GmAGAL, thereby modulating seed oil content. The cyclophilin GmCYP2 interacts with GmGT‐2F and suppresses GmAGAL activation. Haplotype diversity analysis of GmGT‐2F, GmCYP2, and GmAGAL identified favorable haplotype combinations ...

OsFKBP20‐1b stabilizes OsUPF1 and OsUPF2 to promote the degradation of aberrant mRNAs during dehydration stress

Journal of Integrative Plant Biology, EarlyView.
The rice protein OsFKBP20‐1b protects key RNA‐surveillance factors from breakdown, so they can better eliminate defective messages. This RNA quality‐control boost reduces errors and helps plants survive drought, revealing a link between RNA control and drought tolerance.

lincRNA6679 promotes FnPR1B expression via phosphorylation‐activated FnWRKY14 to enhance strawberry resistance to Botrytis cinerea

Journal of Integrative Plant Biology, EarlyView.
In strawberry, Botrytis cinerea induces the expression of the long, intergenic non‐coding RNA lincRNA667，which upregulates the transcription factor gene FnWRKY14. FnWRKY14 then binds to the promoter of the pathogenesis‐related gene FnPR1B, enhancing strawberry resistance to B. cinerea.
