Exploring the dark side of tertiary and quaternary structure dynamics in MtbFBPaseII.

Tuberculosis (TB) is a major global cause of mortality, primarily stemming from latent tuberculosis infection (LTBI). Failure to fully treat LTBI can result in drug-resistant forms of TB. Therefore, it is essential to develop novel drugs with unique mechanisms of action to combat TB effectively. One crucial metabolic pathway in Mycobacterium tuberculosis (Mtb), which contributes to TB infection and persistence, is gluconeogenesis. Within this pathway, the enzyme fructose bisphosphatase (FBPase) plays a significant role and is considered a promising target for drug development. By targeting MtbFBPaseII, a specific class of FBPase, researchers have employed molecular dynamics simulations to identify regions capable of binding new drugs, thereby inhibiting the enzyme's activity and potentially paving the way for the development of effective treatments.Communicated by Ramaswamy H.
