Overview

Review highlights the role of intrinsically disordered proteins in bacterial stress response and fitness, suggesting a novel mechanistic link to antimicrobial resistance and potential drug targets.

Key Points

To examine the biological roles of intrinsically disordered proteins in bacterial fitness and explore their emerging relationship with antimicrobial resistance mechanisms.
Narrative synthesis of current evidence evaluating the prevalence and roles of intrinsically disordered proteins (IDPs) in bacteria.
Analysis of bacterial functional domains including protein secretion pathways, desiccation survival, and stress response cascades.
Identified structural disorder as a critical mechanism enabling bacterial fitness, physiological adaptation, effector secretion, and survival under desiccation and environmental stress.
Proposed intrinsic protein disorder as a central contributor to antimicrobial resistance phenotypes and bacterial evolutionary persistence.
Highlighted bacterial disordered proteins as novel, underutilized molecular targets for future antimicrobial drug design.
