An Investigation Of Alternative Oxidase Presence, Expression, And Regulation In The Moss Physcomitrella Patens, Karina I. Neimanis Jan 2013

An Investigation Of Alternative Oxidase Presence, Expression, And Regulation In The Moss Physcomitrella Patens, Karina I. Neimanis

Theses and Dissertations (Comprehensive)

Alternative oxidase (AOX) is an inner mitochondrial membrane protein that introduces a branch point at ubiquinone within the respiratory electron transport system (ETS). The AOX protein bypasses two sites of proton translocation within the ETS and as a result the yield of ATP per oxygen consumed is significantly reduced. Although AOX appears to be energetically wasteful, recent studies have revealed that AOX has a wide taxonomic distribution. AOX multigene families, transcripts, protein levels, and enzymatic activity have been most thoroughly characterized in many angiosperm (flowering) plants. Given the data available for angiosperm AOXs, evidence of non-angiosperm AOXs in the primary …


Characterization Of G-Patch Motif Contribution To Prp43 Function In The Pre-Messenger Rna Splicing And Ribosomal Rna Biogenesis Pathways, Daipayan Banerjee Jan 2013

Characterization Of G-Patch Motif Contribution To Prp43 Function In The Pre-Messenger Rna Splicing And Ribosomal Rna Biogenesis Pathways, Daipayan Banerjee

Theses and Dissertations--Biology

The DExD/H-box protein Prp43 is essential for two biological processes: nucleoplasmic pre-mRNA splicing and nucleolar rRNA maturation. The biological basis for the temporal and spatial regulation of Prp43 remains elusive. The Spp382/Ntr1, Sqs1/Pfa1 and Pxr1/Gno1 G-patch proteins bind to and activate the Prp43 DExD/H box-helicase in pre-mRNA splicing (Spp382) and rRNA processing (Sqs1, Pxr1). These Prp43-interacting proteins each contain the G-patch domain, a conserved sequence of ~48 amino acids that includes 6 highly conserved glycine (G) residues. Five annotated G-patch proteins in baker’s yeast (i.e., Spp382, Pxr1, Spp2, Sqs1 and Ylr271) and with the possible exception of the uncharacterized Ylr271 …


Refining Molecular Approaches For Bacterial Source Tracking (Bst) In Texas, Joy Truesdale Jan 2013

Refining Molecular Approaches For Bacterial Source Tracking (Bst) In Texas, Joy Truesdale

Open Access Theses & Dissertations

Bacterial source tracking (BST) is a new science that aids in identifying sources of human and animal fecal contamination of environmental water. There are currently two approaches used in BST, library-dependent and library-independent methods. The fecal bacterium E. coli is often used in library dependent methods because it indicates fecal contamination, has been used in human health risk assessments, and has water quality regulatory significance. A disadvantage of E. coli library dependent BST methods is that identification libraries of E. coli isolated from known fecal sources are needed to identify the sources of E. coli isolated from water samples. Further, …
