Project description:Abstract: Vibrio cholerae, the etiological agent of the diarrheal illness cholera, can kill an infected adult in 24 h. V.cholerae lives as an autochthonous microbe in estuaries, rivers and coastal waters. A better understanding of its metabolic pathways will assist the development of more effective treatments and will provide a deeper understanding of how this bacterium persists in natural aquatic habitats. Using the completed V.cholerae genome sequence and PathoLogic software, we created VchoCyc, a pathway-genome database that predicted 171 likely metabolic pathways in the bacterium. We report here experimental evidence supporting the computationally predicted pathways. The evidence comes from microarray gene expression studies of V.cholerae in the stools of three cholera patients [D. S. Merrell, S. M. Butler, F. Qadri, N. A. Dolganov, A. Alam, M. B. Cohen, S. B. Calderwood, G. K. Schoolnik and A. Camilli (2002) Nature, 417, 642-645.], from gene expression studies in minimal growth conditions and LB rich medium, and from clinical tests that identify V.cholerae. Expression data provide evidence supporting 92 (53%) of the 171 pathways. The clinical tests provide evidence supporting seven pathways, with six pathways supported by both methods. VchoCyc provides biologists with a useful tool for analyzing this organism's metabolic and genomic information, which could lead to potential insights into new anti-bacterial agents. VchoCyc is available in the BioCyc database collection (http://BioCyc.org).

Project description:High-resolution tiling analysis of the MR-1 transcriptome under diverse growth conditions The conditions include aerobic growth in Luria-Bertani broth (LB), aerobic growth in defined lactate minimal medium, anaerobic growth in defined lactate minimal medium with 20mM dimethyl sulfoxide as the electron acceptor, anaerobic growth in defined lactate minimal medium with 10mM iron (III) citrate as the electron acceptor, 10 minutes post heat shock at 42oC see GSE39468 for tiling data on lactate minimal media
Project description:Expression data for Desulfovibrio alaskensis strain G20 and mutants in regulator proteins grown on lactate sulfate media and then pelleted and transferred to another media when they reached stationary phase. The Choline mutant was transferred to lacte/sulfate minimal media and choline/sulfate minimal media. The LysX mutant was transferred to minimal media with lysine and rich media. G20 was transferred to minimal media, choline/sulfate minimal media, lactate/choline/sulfate minimal media, minimal media with lysine, and rich media. We aimed to confirm or expand the regulons of each of the transposon interupted regulator mutants and compare gene expression responses of the regulators in different growth conditions.
