Endosymbiotic relationship has great effect on ecological system. Codon and amino acid usages bias of endosymbiotic bacteria Blochmannia floridanus (whose host is an ant Camponotus floridanus) was investigated using experimentally known genes of this organism. Correspondence Analysis on RSCU values show that there exists only one single explanatory major(More)
Chandipura virus, a member of the vesiculovirus genera, has been recently recognized as an emerging human pathogen. Previously, we have shown that Chandipura virus Nucleocapsid protein N is capable of binding to both specific viral leader RNA as well as non-viral RNA sequences, albeit in distinct monomeric and oligomeric states, respectively. Here, we(More)
Amino acid sequences of nucleocapsid proteins are mostly conserved among different rhabdoviruses. The protein plays a common functional role in different RNA viruses by enwrapping the viral genomic RNA in an RNase-resistant form. Upon expression of the nucleocapsid protein alone in COS cells and in bacteria, it forms large insoluble aggregates. In this(More)
NF-kappaB signaling is known to be critically regulated by the NF-kappaB-inducible inhibitor protein IkappaBalpha. The resulting negative feedback has been shown to produce a propensity for oscillations in NF-kappaB activity. We report integrated experimental and computational studies that demonstrate that another IkappaB isoform, IkappaBepsilon, also(More)
Absorption, steady-state fluorescence, steady-state fluorescence anisotropy, and intrinsic and induced circular dichroism (CD) have been exploited to explore the binding of calf thymus DNA (ctDNA) with three cationic phenazinium dyes, viz., phenosafranin (PSF), safranin-T (ST), and safranin-O (SO). The absorption and fluorescence spectra of all the three(More)
Recent studies revealed that the lymphotoxin/lymphotoxin beta receptor (LT)/LTbetaR system activates the noncanonical nuclear factor-kappaB (NF-kappaB) signaling pathway involving I kappa B kinase 1/I kappa B kinase alpha (IKK1/IKKalpha) and NF-kappaB-inducing kinase (NIK) to direct processing of the nfkappab2 protein p100 to yield RelB:p52 complexes.(More)
Fluorescence emission from the single tryptophan residues of two melanocyte stimulating hormones, alpha-MSH and delta-MSH, and their quenching kinetics were studied in aqueous solution and in reverse micelles of AOT/water/isooctane. Incorporation into micelles caused blue shifted and narrower emission peaks, altered quantum yields and considerably enhanced(More)
A total of 171 cases of wounds of various aetiology were examined and screened bacteriologically for evidence of infection by surface swab culture and quantitative full thickness wound biopsy culture techniques. Staphylococcus pyogenes was the most frequently isolated (39.9%) single organism. Other organisms being Escherichia coli (26.1%), Pseudomonas(More)
Inflammatory NF-kappaB/RelA activation is mediated by the three canonical inhibitors, IkappaBalpha, -beta, and -epsilon. We report here the characterization of a fourth inhibitor, nfkappab2/p100, that forms two distinct inhibitory complexes with RelA, one of which mediates developmental NF-kappaB activation. Our genetic evidence confirms that p100 is(More)
Chandipura virus, a member of the rhabdoviridae family and vesiculovirus genera, has recently emerged as human pathogen that is associated with a number of outbreaks in different parts of India. Although, the virus closely resembles with the prototype vesiculovirus, Vesicular Stomatitis Virus, it could be readily distinguished by its ability to infect(More)
