    Description: Mechanisms of DNA repair and mutagenesis are defined on the basis of relatively few proteins acting on DNA, yet the identities and functions of all proteins required are unknown. Here, we identify the network that underlies mutagenic repair of DNA breaks in stressed Escherichia coli and define functions for much of it. Using a comprehensive screen, we identified a network of 〉/=93 genes that function in mutation. Most operate upstream of activation of three required stress responses (RpoS, RpoE, and SOS, key network hubs), apparently sensing stress. The results reveal how a network integrates mutagenic repair into the biology of the cell, show specific pathways of environmental sensing, demonstrate the centrality of stress responses, and imply that these responses are attractive as potential drug targets for blocking the evolution of pathogens.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3782309/" target="_blank"〉〈img src="https://static.pubmed.gov/portal/portal3rc.fcgi/4089621/img/3977009" border="0"〉〈/a〉   〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3782309/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Al Mamun, Abu Amar M -- Lombardo, Mary-Jane -- Shee, Chandan -- Lisewski, Andreas M -- Gonzalez, Caleb -- Lin, Dongxu -- Nehring, Ralf B -- Saint-Ruf, Claude -- Gibson, Janet L -- Frisch, Ryan L -- Lichtarge, Olivier -- Hastings, P J -- Rosenberg, Susan M -- DP1 CA174424/CA/NCI NIH HHS/ -- DP1-CA174424/CA/NCI NIH HHS/ -- F32-GM095267/GM/NIGMS NIH HHS/ -- F32-GM19909/GM/NIGMS NIH HHS/ -- GM66099/GM/NIGMS NIH HHS/ -- GM79656/GM/NIGMS NIH HHS/ -- R01 GM053158/GM/NIGMS NIH HHS/ -- R01 GM079656/GM/NIGMS NIH HHS/ -- R01-GM53158/GM/NIGMS NIH HHS/ -- R01-GM64022/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 2012 Dec 7;338(6112):1344-8. doi: 10.1126/science.1226683.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Molecular and Human Genetics, Baylor College of Medicine, Houston, TX 77030-3411, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/23224554" target="_blank"〉PubMed〈/a〉

    Description: Rapid advances in DNA synthesis techniques have made it possible to engineer viruses, biochemical pathways and assemble bacterial genomes. Here, we report the synthesis of a functional 272,871-base pair designer eukaryotic chromosome, synIII, which is based on the 316,617-base pair native Saccharomyces cerevisiae chromosome III. Changes to synIII include TAG/TAA stop-codon replacements, deletion of subtelomeric regions, introns, transfer RNAs, transposons, and silent mating loci as well as insertion of loxPsym sites to enable genome scrambling. SynIII is functional in S. cerevisiae. Scrambling of the chromosome in a heterozygous diploid reveals a large increase in a-mater derivatives resulting from loss of the MATalpha allele on synIII. The complete design and synthesis of synIII establishes S. cerevisiae as the basis for designer eukaryotic genome biology.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4033833/" target="_blank"〉〈img src="https://static.pubmed.gov/portal/portal3rc.fcgi/4089621/img/3977009" border="0"〉〈/a〉   〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4033833/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Annaluru, Narayana -- Muller, Heloise -- Mitchell, Leslie A -- Ramalingam, Sivaprakash -- Stracquadanio, Giovanni -- Richardson, Sarah M -- Dymond, Jessica S -- Kuang, Zheng -- Scheifele, Lisa Z -- Cooper, Eric M -- Cai, Yizhi -- Zeller, Karen -- Agmon, Neta -- Han, Jeffrey S -- Hadjithomas, Michalis -- Tullman, Jennifer -- Caravelli, Katrina -- Cirelli, Kimberly -- Guo, Zheyuan -- London, Viktoriya -- Yeluru, Apurva -- Murugan, Sindurathy -- Kandavelou, Karthikeyan -- Agier, Nicolas -- Fischer, Gilles -- Yang, Kun -- Martin, J Andrew -- Bilgel, Murat -- Bohutski, Pavlo -- Boulier, Kristin M -- Capaldo, Brian J -- Chang, Joy -- Charoen, Kristie -- Choi, Woo Jin -- Deng, Peter -- DiCarlo, James E -- Doong, Judy -- Dunn, Jessilyn -- Feinberg, Jason I -- Fernandez, Christopher -- Floria, Charlotte E -- Gladowski, David -- Hadidi, Pasha -- Ishizuka, Isabel -- Jabbari, Javaneh -- Lau, Calvin Y L -- Lee, Pablo A -- Li, Sean -- Lin, Denise -- Linder, Matthias E -- Ling, Jonathan -- Liu, Jaime -- Liu, Jonathan -- London, Mariya -- Ma, Henry -- Mao, Jessica -- McDade, Jessica E -- McMillan, Alexandra -- Moore, Aaron M -- Oh, Won Chan -- Ouyang, Yu -- Patel, Ruchi -- Paul, Marina -- Paulsen, Laura C -- Qiu, Judy -- Rhee, Alex -- Rubashkin, Matthew G -- Soh, Ina Y -- Sotuyo, Nathaniel E -- Srinivas, Venkatesh -- Suarez, Allison -- Wong, Andy -- Wong, Remus -- Xie, Wei Rose -- Xu, Yijie -- Yu, Allen T -- Koszul, Romain -- Bader, Joel S -- Boeke, Jef D -- Chandrasegaran, Srinivasan -- 092076/Wellcome Trust/United Kingdom -- GM077291/GM/NIGMS NIH HHS/ -- R01 GM077291/GM/NIGMS NIH HHS/ -- R01 GM090192/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 2014 Apr 4;344(6179):55-8. doi: 10.1126/science.1249252.
