Reversible protein phosphorylation is a prevalent signaling mechanism which modulates cellular metabolism in response to changing environmental conditions. In this study, we focus on previously uncharacterized Mycobacterium tuberculosis Ser/Thr protein kinase (STPK) PknJ, a putative transmembrane protein. PknJ is shown to possess autophosphorylation(More)
BACKGROUND The integrated functions of 11 Ser/Thr protein kinases (STPKs) and one phosphatase manipulate the phosphorylation levels of critical proteins in Mycobacterium tuberculosis. In this study, we show that the lone Ser/Thr phosphatase (PstP) is regulated through phosphorylation by STPKs. PRINCIPAL FINDINGS PstP is phosphorylated by PknA and PknB and(More)
Chickpea is the world’s third most important legume crop and belongs to Fabaceae family but suffered from severe yield loss due to various biotic and abiotic stresses. Development of modern genomic tools such as molecular markers and identification of resistant genes associated with these stresses facilitate improvement in chickpea breeding towards abiotic(More)
Virulence is described as an ability of an organism to infect the host and cause a disease. Virulence factors are the molecules that assist the bacterium colonize the host at the cellular level. These factors are either secretory, membrane associated or cytosolic in nature. The cytosolic factors facilitate the bacterium to undergo quick adaptive—metabolic,(More)
The present work reveals the response of different doses of selenium (Se) and alleviating effect of salicylic acid (SA) on Se-stressed Brassica juncea seedlings. Selenium, a micronutrient, is essential for both humans and animals but is toxic at higher doses. Its beneficial role for the survival of plants, however, is still debatable. On the other hand, SA,(More)
BACKGROUND Mycobacterium ulcerans, the causative agent of Buruli ulcer in humans, is unique among the members of Mycobacterium genus due to the presence of the virulence determinant megaplasmid pMUM001. This plasmid encodes multiple virulence-associated genes, including mup011, which is an uncharacterized Ser/Thr protein kinase (STPK) PknQ. (More)
– Many emerging mobile wireless applications use symmetric keys for secure multicast communication. This key has to be changed every time a user decides to leave or join the network. We introduce a novel hierarchical security framework for mobile Ad Hoc Multicast networks in which data encryption is done using a symmetric key and key establishment using(More)
