  • PubMed Abstract: 

    Thioredoxin (Trx) is a central component of the redox control system that maintains the redox homeostasis critical for organism survival. Owing to its central role in survival, Trx is a prospective target for novel antimicrobial agents. Herein, we report a 1.45 Å high-resolution structure of Trx1 of Acinetobacter baumannii (abTrx1), an antibiotic-resistant pathogenic superbug. Although abTrx1 exhibited the canonical Trx fold, which consists of a four-stranded β-sheet surrounded by four α-helices, structural differences were detected in the loop forming the C-X-X-C redox center and the C-terminal. The unique CAPC sequence of the C-X-X-C motif in the abTrx1 redox center was characterized by mutagenesis. This study contributes to the field of drug designing against superbugs.
