PTEN homozygous deletion is a negative prognostic factor in tumor treating fields‐treated glioblastoma, IDH wildtype patients

Brain Pathology, EarlyView.
In a molecularly confirmed cohort of 64 newly diagnosed, TTFields‐treated glioblastomas, IDH‐wildtype, homozygous PTEN deletion was associated with markedly shorter overall survival (368 vs. 603 days) and remained an independent adverse prognostic factor.

Register Shifts in Uracil-Damaged DNA

Uracil is a highly mutagenic and common lesion of DNA, which is caused by misincorporation or spontaneous deaminating of cytosine. Uracil will spontaneously base flip, breaking its Watson-Crick hydrogen bonds and base stacking and leaving the helix stack.

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

The 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.

Transgenic selection and underlying mechanisms in apicomplexan parasites

The FEBS Journal, EarlyView.
Transgenic selection markers have driven genetic engineering in apicomplexans, enabling precise, iterative experiments. This review discusses mechanistic details of drug selection markers, strategies for marker recycling, and practical considerations for several clinically relevant parasites.

Blocking protein quality control degradation leads to structural stabilization of DHFR indel variants

The FEBS Journal, EarlyView.
Blocking protein quality control degradation by deleting the E3 ligases Ubr1 or San1 stabilizes many DHFR insertion and deletion variants that are otherwise partially unfolded. These hypomorphic variants regain folding at lower temperatures or upon methotrexate binding, revealing that PQC degradation can remove proteins that are still functionally ...

Functional and transcriptomic analyses in Neurospora crassa reveal a crucial role for the N‐glycoprotein deglycosylation process in fungal homeostasis

The FEBS Journal, EarlyView.
In Neurospora crassa, a cytosolic GH18 endo‐β‐n‐acetylglucosaminidase (ENGase) functions as an active deglycosylating enzyme. Deletion of this severely alters tolerance to multiple stress conditions and causes extensive transcriptomic reprogramming, including upregulation of a GH20 exo‐β‐n‐acetylhexosaminidase under ER stress, indicating that N. crassa

Structural insights into xyloglucan recognition by an ABC transporter from a Gram‐positive, thermophilic bacterium

The FEBS Journal, EarlyView.
Athe_2052 is an ABC transporter substrate‐binding protein that recognizes xyloglucan heptasaccharide (XXXG), a soluble breakdown product of plant xyloglucan. The crystal structure of Athe_2052, together with binding assays and computational modeling, shows how XXXG is recognized by this sugar transporter.

Rescue of pATOM36‐depleted T. brucei by human MTCH1/2 reveals common features of protein insertases

The FEBS Journal, EarlyView.
Human MTCH1 and MTCH2 (with an N‐terminal extension) functionally complement the loss of pATOM36 in T. brucei, indicating that these evolutionarily distant proteins recognize a common set of substrates and share fundamental principles of mitochondrial outer membrane protein insertion. Structural analyses reveal a common hydrophilic cavity, supporting a

Divergent roles of ent‐kaurene oxidase paralogs in rice momilactone biosynthesis

Journal of Integrative Plant Biology, EarlyView.
Rice contains a five‐gene tandem array of genes encoding members of the ent‐kaurene oxidase (KO) family, with OsKOL4 and OsKOL5 playing divergent roles in momilactone metabolism, but both acting in the production of antifungal and antibacterial phytoalexins, which are important for disease resistance.
