The proteomic and transcriptomic responses to iron, sulfur, and nitrogen limitation in the abundant marine bacterium Candidatus Pelagibacter ubique

Creator:: Smith, Daniel P.
Abstract:: Batch cultures of Candidatus Pelagibacter ubique were grown under iron-, organosulfur-, and nitrogen-limiting conditions to understand how this ubiquitous marine bacterium responds to and interacts with environments where growth is limited by the availability of these nutrients. Global gene expression was monitored using microarrays and quantitative mass spectrometry to observe...

Regulation of ribonucleotide reductase analyzed by simultaneous measurement of the four enzyme activities

Creator:: Hendricks, Stephen P.
Abstract:: The first committed step in DNA biosynthesis occurs by direct reduction of ribonucleotides. This reduction is catalyzed by ribonucleotide reductase (RNR), an enzyme which uses a unique radical mechanism to facilitate the transformation. All four DNA precursors are synthesized by a single enzyme. Therefore, an intricate pattern of regulation has...

Iron acquisition and its regulation in Nitosomonas europaea

Creator:: Vajrala, Neeraja
Abstract:: Iron is absolutely necessary for the maintenance, the defense, the differentiation and last, but by no means least, the growth and cellular division of almost all living organisms including Nitrosomonas europaea, an ammonia oxidizing bacterium. Given the necessity of iron, it is not surprising that N. europaea evolved several irondependent...

Regulation of inositol phospholipid hydrolysis by extended treatment with angiotensin II in human aortic smooth muscle cells

Creator:: Niibori, Yoshiko
Abstract:: Long-term stimuli of many systems leads to decreased cellular responsiveness, or desensitization. We characterized the desensitization of angiotensin II (Ang 11)-mediated inositol phospholipid (IP) hydrolysis in cultured human aortic smooth muscle cells (HASMC). Although it has been suggested that the desensitization induced by long-term Mg II exposure may result partially...

Regulation of exopolysaccharide synthesis

Creator:: Dierksen, Karen P.
Abstract:: Lactococcus lactis subsp. cremoris Ropy 352 and L. lactis subsp. cremoris Hollandicus produce an exopolysaccharide (EPS) that imparts commercially desirable textural and rheological properties to fermented milk products. This ropy phenotype is expressed under specific environmental conditions. A mucoid EPS phenotype, also expressed under specific environmental conditions, but not involved...

Aerobic cometabolism of 1,1,1-trichloroethane and 1,1-dichloroethene by a bioaugmented butane-utilizing culture in a continuous flow column

Creator:: Maremanda, Bhargavi
Abstract:: The transformation of 1,1,1 -trichioroethane (1,1,1 -TCA) and 1,1 -dichioroethene (1,1 - DCE) was evaluated in a continuous flow column reactor using a mixed culture that grew on butane. The column was packed with aquifer materials and groundwater obtained from the in-situ bioremediation test site at Moffett Field, CA. The...

Microcosm studies of bioaugmentation with a butane-utilizing mixed culture : microbial community structure and 1,1-DCE cometabolism

Creator:: Lim, Hee Kyung
Abstract:: The 1,1-dichloroethene (1,1-DCE) cometabolic transformation abilities of indigenous and bioaugmented microorganisms were compared in microcosms constructed with groundwater and aquifer solids from the Moffett Field site, CA. Microbial community structure in the microcosms and possible community shifts due to 1,1-DCE transformation stress was evaluated by terminal restriction fragment length polymorphism...

Transcriptional networks controlled by the fatty acid regulators FAR-1 and FAR-2

Creator:: Bredeweg, Erin L.
Abstract:: Fungi are capable of growth on a wide variety of carbon sources, both living and dead. They can produce an arsenal of enzymes and transporters for harvesting sugars, polysaccharides, amino acids, lipids and micronutrients from their environments [1]. Within the nucleus of a cell, transcription factors (TF) control whether genes...
