MabR (), a PucR-type transcription factor, plays a crucial role in regulating mycolic acid biosynthesis in . To understand its regulatory mechanisms, we determined the crystal structures of its N-terminal and C-terminal domains. The N-terminal domain adopts a globin-like fold, while the C-terminal domain comprises an α/β GGDEF domain and an all-α effector domain with a helix-turn-helix DNA-binding motif.

Using as a model for , we determined the physiologically significant delayed death effect induced by doxycycline [IC, 1,401 ± 607 nM]. As expected, IC to chloroquine (20.

The ST258 classical (c)Kp strain is dominant in hospital-acquired infections in North America and Europe, while ST23 hypervirulent (hv)Kp prevails in community-acquired infections in Asia. This study aimed to develop symptomatic mucosal infection models in mice that mirror natural infections in humans to gain a deeper understanding of Kp mucosal pathogenesis.
