Mycobacterium tuberculosis WhiB3 responds to O2 and nitric oxide via its [4Fe-4S] cluster and is essential for nutrient starvation survival
Amit Singh,Loni Guidry,K. V. Narasimhulu,Deborah Mai,John E. Trombley,Kevin Redding,Gregory I. Giles,Gregory I. Giles,Jack R. Lancaster,Adrie J. C. Steyn +9 more
TL;DR: It is shown that Mtb WhiB3 responds to the dormancy signals NO and O2 through its iron-sulfur (Fe-S) cluster, and EPR analysis demonstrates that NO forms a protein-bound dinitrosyl–iron–dithiol complex with the Fe-S cluster, indicating that NO specifically targets the WhiBs 3Fe-4S cluster.
Journal ArticleDOI
Multi-layer security of medical data through watermarking and chaotic encryption for tele-health applications
TL;DR: Experimental results clearly indicated that the proposed technique is highly robust and sufficient secure for various forms of attacks without any significant distortions between watermarked and cover image.
Journal ArticleDOI
Reengineering redox sensitive GFP to measure mycothiol redox potential of Mycobacterium tuberculosis during infection
Ashima Bhaskar,Manbeena Chawla,Mansi Mehta,Pankti Parikh,Pallavi Chandra,Devayani Bhave,Dhiraj Kumar,Kate S. Carroll,Amit Singh +8 more
TL;DR: In this article, a real-time image of mycothiol redox potential (EMSH) within Mtb cells during infection was used to measure the changes in intramycobacterial EMSH with unprecedented sensitivity and specificity.
Journal ArticleDOI
An improved DWT-SVD domain watermarking for medical information security
Ashima Anand,Amit Singh +1 more
TL;DR: Experimental results demonstrate that the suggested watermarking technique archives high robustness against attacks in comparison to the other scheme for medical images, and verification its robustness for various attacks while maintaining imperceptibility, security and compression ratio.
Journal ArticleDOI
Dissecting virulence pathways of Mycobacterium tuberculosis through protein–protein association
TL;DR: A simple system based upon the functional reconstitution of two small murine dihydrofolate reductase domains independently fused to two interacting proteins that will be a major contributor to the systematic assembly of mycobacterial protein interaction maps that will lead to the development of better strategies for the control of tuberculosis.
