Mycobacterium tuberculosis WhiB3 responds to O 2 and nitric oxide via its [4Fe-4S] cluster and is essential for nutrient starvation survival

Autor: Gregory I. Giles, Amit Singh, Loni Guidry, K. V. Narasimhulu, Deborah Mai, Jack R. Lancaster, Kevin Redding, John E. Trombley, Adrie J. C. Steyn

Publikováno v: Proceedings of the National Academy of Sciences. 104:11562-11567

A fundamental challenge in the redox biology of Mycobacterium tuberculosis ( Mtb ) is to understand the mechanisms involved in sensing redox signals such as oxygen (O 2 ), nitric oxide (NO), and nutrient depletion, which are thought to play a crucial

EPR and optical absorption spectra of VO2+ions in calcium oxalate monohydrate single crystals

Autor: J. Lakshmana Rao, K. V. Narasimhulu, V. Padmavathi, Y. N. Naidu

Publikováno v: Radiation Effects and Defects in Solids. 143:193-201

Electron paramagnetic resonance (EPR) and Optical absorption spectra of vanadyl ions in calcium oxalate monohydrate single crystals have been studied. EPR spectrum at room temperature exhibits an isotropic octet spectrum. The detailed EPR analysis in

Phenanthroline−Polyoxometalate Hybrid Compounds and the Observation of Intramolecular Charge Transfer

Autor: K. V. Narasimhulu, Itsik Bar-Nahum, Ronny Neumann, Lev Weiner

Publikováno v: Inorganic Chemistry. 44:4900-4902

A phenanthroline ligand has been covalently modified at the 2 and 9 positions by an aminophenylhexamolybdate substituent. The 1H NMR spectrum indicated a strong electron-withdrawing effect of the hexamolybdate (Mo6O19(2-)) moiety on the phenanthrolin

Mycobacterium tuberculosis WhiB4 regulates oxidative stress response to modulate survival and dissemination in vivo

Autor: Mansi Mehta, Kevin Redding, Nimi Vashi, Manbeena Chawla, Pankti Parikh, Anup Srivastava, Amit Singh, Adrie J. C. Steyn, Dhiraj Kumar, MohamedHusen Munshi, K. V. Narasimhulu, Alka Saxena, Deborah Mai

Publikováno v: Molecular Microbiology

Host-generated oxidative stress is considered one of the main mechanisms constraining Mycobacterium tuberculosis (Mtb) growth. The redox-sensing mechanisms in Mtb are not completely understood. Here we show that WhiB4 responds to oxygen (O2) and nitr
