It is shown that PhoP regulates the transcription of α‐crystallin 2 (acr2), expression of which increases more than any other gene of M. tuberculosis during heat‐shock or following macrophage infection.

A model is proposed to suggest that PhoP–SigE interaction represents a major requirement for the global acid stress response, absence of which leads to strongly reduced survival of the bacilli under acidic pH conditions.
EspR-dependent ESAT-6 Protein Secretion of Mycobacterium tuberculosis Requires the Presence of Virulence Regulator PhoP*

- 21 July 2016
A model is proposed suggesting how PhoP and EspR protein-protein interactions contribute to activation of espACD expression and, in turn, control ESAT-6 secretion, an essential pathogenic determinant of M. tuberculosis.
Unique N-terminal Arm of Mycobacterium tuberculosis PhoP Protein Plays an Unusual Role in Its Regulatory Function*
- Arijit Das, V. A. Kumar, R. R. Sevalkar, R. Bansal, D. Sarkar
- BiologyJournal of Biological Chemistry
- 20 August 2013
It is proposed that the N-terminal arm is an adaptable structural feature of M. tuberculosis PhoP, which evolved to fine-tune regulatory capabilities of the transcription factor in response to the changing physiology of the bacilli within its host.
INFLUENCE OF SALT STRESS CONDITIONS ON CALCITE FORMATION BY CALCIFYING BACTERIA ISOLATED FROM SALINE ENVIRONMENT
Surface treatments play an important role in the protection of construction materials from the ingress of water and other deleterious substances. Due to the negative side effects of some of the…
