The emergence of antibiotic resistance has significantly elevated the threat posed by Acinetobacter baumannii as an opportunistic pathogen. A.baumannii, a notorious bacterium, poses a serious threat to health care, leading to severe nosocomial infections, particularly in immunocompromised individuals.

Lymphatic filariasis is a parasitic disease caused by the worms Wuchereria bancrofti, Brugia malayi and Brugia timori. Three anti-filarial drugs namely Diethylcarbamazine, Ivermectin and Albendazole and their combinations are used as the control strategies for filariasis. The disease has received much attention in drug discovery due to the unavailability of vaccines and the toxic pharmaceutical properties of the existing drugs.

Article Synopsis
  • A phylogenetic tree was created using 1854 sequences of Lrp/AnsC (FFRPs) and ArsR proteins to study the differences in their functions as transcriptional regulators and de-repressors in response to amino acids and metal ions.
  • Structural modeling of 134 sequences revealed high similarity between some ArsR and FFRP proteins, with common Helix-turn-Helix domains, but distinct ligand-binding domains suggesting different binding preferences.
  • The study included molecular modeling and functional tests, revealing how PH0140 and TtArsR proteins can be potential bio-sensors for Tryptophan and Cu ions, highlighting their structural evolution and distinct functions.
