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.

Chemoenzymatic Radiosynthesis of a Gluconate Transporter‐Targeted In Vivo Bacterial Sensor From Clinical [18F]FDG

Angewandte Chemie, EarlyView.
An efficient radiosynthesis of fluorine‐18 labeled gluconic acid ([18F]FGA) was developed using two readily available materials, 2‐deoxy‐2‐[18F]fluoro‐D‐glucose ([18F]FDG) and glucose oxidase. [18F]FGA is highly specific for bacterial gluconate metabolism mediated by gluconate permease (GntP) and gluconate kinase (GntK), with rapid clearance, low off ...

The crystal structure of the Borrelia burgdorferi nicotinamidase BBE22 resolves a long‐standing annotation error

FEBS Open Bio, EarlyView.
The crystal structure of Borrelia burgdorferi nicotinamidase (PncA/BBE22) reveals the correct full‐length protein initiated from a non‐canonical AUU start codon. The structure validates previous biochemical findings and resolves a long‐standing annotation error, demonstrating that the truncated database sequence is structurally incompatible with the ...

Streptavidins Coordinate Biotin Sequestration and Self‐Resistance Within a Biotin‐Pathway Antibiotic Network

Advanced Science, EarlyView.
A conserved genomic region between two streptavidin genes in Streptomyces packages biosynthetic gene clusters for diverse biotin‐pathway antibiotics: acidomycin, stravidin, the new non‐proteinogenic amino acid ANDA, and the new BioA inhibitor α‐methyl‐KAPA.
