An unexpected alternative viologen electron mediator site in tungsten‐containing formate dehydrogenase

FEBS Letters, EarlyView.
An unexpected alternative interaction site for ethyl viologen was identified in formate dehydrogenase 1 from Methylorubrum extorquens. Combined mutagenesis, kinetic analysis, and docking revealed that aromatic residues near an iron–sulfur cluster enable flavin mononucleotide‐independent electron transfer, offering a framework for engineering improved ...

Nucleotide sequence and genomic organization of Acyrthosiphon pisum virus

, 1997
The nucleotide sequence of the genomic RNA of Acyrthosiphon pisum virus was determined. The APV genome is 10,016 nucleotides in length, excluding the 3′-end poly(A) track, and contains two large open reading frames (ORFs), encoding proteins of 296,340 ...

From mice to humans—divergent strategies for intestinal homeostasis and regeneration

FEBS Letters, EarlyView.
Recent advances such as organoid genome editing, xenotransplantation, imaging, and whole‐genome sequencing have enabled direct studies of human intestinal stem cells (ISCs). These studies reveal species‐specific features, including slower ISC proliferation, distinct injury responses, slower somatic mutation accumulation in humans, and an inverse ...

Sequence organization: Understanding what drives talk

, 2020
Sequence organization was the pioneering insight that gave rise to conversation analysis (CA) and it remains the primary assumption in CA studies about how discourse is structured and how speakers manage their talk.

Sequence and structural organization of murine cytomegalovirus immediate-early gene 1 [PDF]

, 1987
In murine cytomegalovirus, abundant immediate-early transcription originates from 0.769 to 0.815 map units of the genome. This region contains the immediate-early gene (gene ieI) which encodes pp89, a phosphoprotein active in transcriptional regulation ...

Phosphoinositides and inositol phosphates as molecular glues

FEBS Letters, EarlyView.
Inositol phosphates (IPs) and phosphoinositides (PIPs) regulate diverse eukaryotic processes. Beyond recruiting signaling proteins or acting as structural cofactors, recent studies suggest they mediate protein–protein interactions as natural molecular glues.

Structural insights and therapeutic targets in Acinetobacter baumannii capsule biosynthesis

FEBS Letters, EarlyView.
Hypervirulent KL49 A. baumannii's capsular polysaccharide contains the nonulosonic acid 8‐epi‐Leg5,7Ac2, synthesized by epimerization via ElaA, ElaB, and ElaC. Crystal structures of ElaA, ElaB, and ElaC reveal their role in CMP‐Leg5,7Ac2 synthesis and regioselective C8 epimerization.
