This work provides the first “omics” scale assessment of the oxidative stress response for an archeal organism and together with a network analysis using data from previous studies on bacteria and eukaryotes reveals evolutionarily conserved pathways where complex and overlapping defense mechanisms protect against oxygen toxicity.Ĭitation: Maaty WS, Wiedenheft B, Tarlykov P, Schaff N, Heinemann J, Robison-Cox J, et al. Despite the central role played by DPSL, cells maintained a lower level of protection after disruption of the dpsl gene, indicating a level of redundancy in the oxidative stress pathways of S. A scheme for the ability of this complex to perform multi-step reactions is presented. Three of these, DPSL, superoxide dismutase, and peroxiredoxin were shown to interact and likely form a novel supramolecular complex for mitigating oxidative damage. As expected, a number of antioxidant related mRNAs and proteins were differentially regulated. A recently characterized ferritin-like antioxidant protein, DPSL, was the most highly regulated species of mRNA and protein, in addition to being post-translationally modified. Parallel proteomic analyses using two-dimensional differential gel electrophoresis (2D-DIGE), monitored more than 800 proteins 30 and 105 minutes after exposure and found that 18 had significant changes in abundance. Microarray analysis of mRNA expression showed that 102 transcripts were regulated by at least 1.5 fold, 30 minutes after exposure to 30 µM H 2O 2. In this study transcriptome, proteome, and chemical reactivity analyses of hydrogen peroxide (H 2O 2) induced oxidative stress in Sulfolobus solfataricus (P2) were conducted. However, in comparison to bacteria and eukaryotes, relatively little is known about the biology and biochemistry of archaea in response to changing conditions and repair of oxidative damage. Archaea have adapted to some of the most extreme environments known to support life, including highly oxidizing conditions. Down I go anyway, to this journey’s end down the river of history.To avoid molecular damage of biomolecules due to oxidation, all cells have evolved constitutive and responsive systems to mitigate and repair chemical modifications. A sign on the other side of the gate says this is public access, but a passing member of the home’s staff doesn’t think it is, any more. I envy the residents their view, and consider sneaking into a gazebo for an eyeful across the Rideau into Vanier, when I hear the mail deliverer again and see that she has paused by a gated set of steps leading down to a small patio overlooking the river. The selling price to the Algerians was a local real estate record, but then what’s money.Ī retirement home stands in what were once the Fleck/Paterson grounds. A couple of developers took a go at doing something with it, but then the Maharishi Heaven on Earth development corporation picked it up and spirited a lot of money into it before giving up and it went into its present incarnation. Gertrude Fleck stayed in the house till 1940, then sold to a senator, Norman Paterson, who was in there until his death in 1983, aged 99. Fleck became a major local philanthropist in his later years -you’ll recognize the Andrew Fleck Child Care Services. The husband, Andrew Fleck, who managed some of Booth’s mills and his railway, the Canadian Atlantic, no doubt enjoyed a few cigars with the view.
The lumber guys liked to have their houses built with a river view (as Bronson did at the end of Wellington). It took two years to build and was completed in 1903. Booth, had the house built for his daughter and her husband, like you do, and got the Ottawa architect and artist John Watts to design it. Though it is now the Algerian Embassy, this palatial place has been the repository of quite a chunk of Ottawa history. It’s a terracotta masterpiece of turrets and tiling and fancy brickwork. The other side of Charlotte consists of a tidy row of town houses on the north side, and one heck of a home on the other at number 500. To my right, the Russian Embassy is quiet on the outside and no doubt busy processing mega data on the inside. More big houses, more embassies, and then I am at Charlotte Street. On one of then President de Gaulle’s later visits in 1960, he was not so warmly greeted in Ottawa, though he was in Quebec. The house was then the Canadian HQ of the provisional government of the Republic of France, awaiting liberation.
A plaque tells me that General Charles de Gaulle visited here on July 14, 1944. Next door to a house undergoing renovation, where a workman has the radio up to bird-stunning volume, is a relatively plain grey house set well back.
