# Understanding properties of the master effector of phage shock operon in Mycobacterium tuberculosis via bioinformatics approach

## TL;DR

This paper explores the role of the PspA protein in the phage shock operon of Mycobacterium tuberculosis using bioinformatics methods.

## Contribution

The study models and simulates PspA's conformational changes in M. tuberculosis, revealing structural transitions.

## Key findings

- PspA undergoes significant conformational transitions at the far end in Mycobacterium tuberculosis.
- The structural behavior of PspA influences the overall function of the Psp system.
- The study is investigating the impact of phosphorylation and structural fluctuations during PspA complex formation.

## Abstract

The phage-shock-protein (psp) is a part of the psp operon, which assists in safeguarding the survival of bacterium in stress and shields the cell against proton motif force challenge. It is strongly induced by bacterium allied phages, improperly localized mutant porins and various other stresses. Master effector of the operon, PspA has been modeled and simulated, illustrating how it undergoes significant conformational transition at the far end in Mycobacterium tuberculosis. Association of this key protein of the operon influences action of Psp system on the whole. We are further working on the impact of phosphorylation perturbation and the impact of structural fluctuations during complex formation of PspA with other moieties of interest.
