Summary Lipid peroxidation may be initiated either by lipoxygenases or reactive oxygen species (ROS). Enzymatic oxidation of α‐linolenate can result in the biosynthesis cyclic oxylipins jasmonate type while free‐radical‐catalyzed yield several classes termed phytoprostanes vivo . Previously, we have shown that one these classes, E 1 ‐phytoprostanes (PPE ), occurs ubiquitously plants. In this work, it is PPE are converted to novel cyclopentenone A ‐ and B (PPA PPB ) planta Enhanced formation...
Abstract Silicon (Si) has attracted substantial attention because of its beneficial effect on plants during abiotic stress, including stress due to arsenic (As). We here report that priming rice seeds with As and Si together, helped the plant sustain for longer period. examined induced tolerance against in seedlings at short (7 d) long (15 exposure periods under (III) treatments since their germinating stage. Results showed expression transporter genes OsLsi1 , OsLsi2 OsLsi6 was more +...
Abstract The present work describes the in vitro synthesis and characterization of Zinc oxide nanoparticles (ZnO NPs) using an enzyme alpha amylase, synthesized were used to study their beneficial effect growth development Brassica juncea . Transmission Electron Microscope (TEM) image reveals average size ZnO NPs was 11 nm X-ray powder diffraction (XRD) suggests crystalline nature. In-silico confirmed lysine, glutamine tyrosine amylase enzyme, plays a crucial role reduction acetate dihydrate...
ABSTRACT EmbR, a putative transcriptional regulator from Mycobacterium tuberculosis , is homologous to the OmpR class of regulators that possess winged helix-turn-helix DNA binding motifs. In contrast other OmpR-like response are usually phosphorylated and controlled by histidine kinases, EmbR was recently shown be cognate mycobacterial serine/threonine kinase PknH. Despite in vitro evidence phosphorylation interaction between regulator, physiological function PknH-EmbR pair still unknown....
During protein synthesis, translation elongation factor Tu (Ef-Tu) is responsible for the selection and binding of cognate aminoacyl-tRNA to acceptor site on ribosome. The activity Ef-Tu dependent its interaction with GTP. Posttranslational modifications, such as phosphorylation, are known regulate in several prokaryotes. Although a study Mycobacterium tuberculosis phosphoproteome showed be phosphorylated, role phosphorylation regulation has not been studied. In this report, we show that M....
Mycobacterium tuberculosis encodes for 11 eukaryotic-like serine/threonine protein kinases. Genetic and biochemical studies show that these kinases regulate various cellular processes including cell shape morphology, glucose glutamine transport, phagosome-lysosome fusion the expression, and/or activity of transcription factors. PknK is largest predicted kinase in M. tuberculosis. Here, we have cloned, overexpressed, purified K (PknK) to near homogeneity its ability phosphorylate proteins...
ABSTRACT HU, a widely conserved bacterial histone-like protein, regulates many genes, including those involved in stress response and virulence. Whereas ample data are available on HU-DNA communication, the knowledge how HU perceives signal transmit it to DNA remains limited. In this study, we identify HupB, homolog of human pathogen Mycobacterium tuberculosis , as component serine/threonine protein kinase (STPK) signaling. HupB is extracted its native state from exponentially growing cells...
Abstract Little is known about the interactive effects of exogenous nitric oxide (NO) and abscisic acid (ABA) on nitrogen (N) metabolism related changes at molecular biochemical levels under drought stress. The present study highlights independent combined effect NO ABA (grouped as “nitrate agonists”) expression profiles representative key genes to be involved in N-uptake assimilation, together with proline metabolism, N–NO enzyme’s activity nutrient content polyethylene glycol (PEG) treated...
Phosphorylation of the mycobacterial transcriptional activator, EmbR, is essential for regulation embCAB operon encoding cell wall arabinosyltransferases. This signaling pathway eventually affects resistance to ethambutol (a frontline antimycobacterial drug) and Lipoarabinomannan/Lipomannan ratio (an important determinant averting host immune response). In this study, further biochemical characterization revealed that as a regulator, interacts with RNA polymerase possesses...
