Novel cellulases from an extremophilic filamentous fungi Penicillium citrinum: production and characterization
TLDR
The present work reports for the first time, the alkali stable cellulase from alkali tolerant fungus Penicillium citrinum, which may have potential effectiveness as additives to laundry detergents. Expand
Control of RNP motility and localization by a splicing-dependent structure in oskar mRNA
TLDR
In vivo analysis reveals that splicing creates the spliced oskar localization element (SOLE), whose structural integrity is crucial for ribonucleoprotein motility and localization in the oocyte, and that the SOLE complements the EJC in formation of a functional unit that maintains proper kinesin-based motility of Oskar mRNPs and posterior mRNA targeting. Expand
Distinct Dimer Interaction and Regulation in Nitric-oxide Synthase Types I, II, and III*
TLDR
The results indicate that the three NOS isozymes, despite their general structural similarity, differ markedly in their strengths, interfaces, and in how l-Arg and H4B influence their formation and stability. Expand
Role of superoxide dismutase in survival of Leishmania within the macrophage.
TLDR
Results indicate that SOD is a major determinant of intracellular survival of Leishmania, and cloned a SOD gene from L. tropica and generated SOD-deficient parasites by expressing the corresponding antisense RNA from an episomal vector. Expand
Mechanistic Studies with Potent and Selective Inducible Nitric-oxide Synthase Dimerization Inhibitors*
TLDR
The selectivity for inhibiting dimerization of iNOS versus endothelial and neuronal NOS suggests that the energetics and kinetics of monomer-dimer equilibria are substantially different for the mammalian NOS isoforms. Expand
Effect of nitrosative stress on Schizosaccharomyces pombe: inactivation of glutathione reductase by peroxynitrite.
TLDR
This is the first report of S-nitrosoglutathione (GSNO) reductase activity in S. pombe and its inactivation by GSNO and the inactivation of GR and glutathione peroxidase in the presence of various reactive nitrogen species in vivo. Expand
Nitric Oxide Production by Necrotrophic Pathogen Macrophomina phaseolina and the Host Plant in Charcoal Rot Disease of Jute: Complexity of the Interplay between Necrotroph–Host Plant Interactions
TLDR
Interestingly, M. phaseolina was found to produce nitric oxide which was detected in vitro inside the mycelium and in the surrounding medium and may have important physiological significance in necrotrophic host pathogen interaction. Expand
The EJC Binding and Dissociating Activity of PYM Is Regulated in Drosophila
TLDR
It is shown that elevated amounts of the Drosophila PYM (DmPYM) N-terminus during oogenesis cause dissociation of EJCs from oskar RNA, resulting in its mislocalization and consequent female sterility and its loss of function is lethal to flies with reduced y14 or mago gene dosage. Expand
Purification and properties of mercuric reductase from Azotobacter chroococcum
Mercury resistance determinants in bacteria are often plasmid‐borne or transposon‐mediated. Mercuric reductase, one of the proteins encoded by the mercury resistance operon, catalyses a uniqueExpand
Regulation of cell cycle and stress responses under nitrosative stress in Schizosaccharomyces pombe.
TLDR
A novel molecular mechanism of cell cycle control under nitrosative stress is proposed based on the experimental results and bioinformatics analysis of the fission yeast Schizosaccharomyces pombe. Expand
