Structural And Functional Studies Of The Tryptophan Operon Of Bacillus Pumilus, Miriam V. Rivas

Dissertations, Theses, and Capstone Projects

The nucleotide sequence of the trpE, trpD, and 5’trpC genes of the Bacillus pumilus tryptophan operon was determined for a comparative evaluation. DNA comparisons to the tryptophan operon of a related species, Bacillus subtilis, showed 66% base homology. The overlapping of translational start and stop signals indicate that, similar to Escherichia coli, the trpE, trpD, and trpC genes of the B.pumilus trp operon are translationally coupled. The values for amino acid identity between the two Bacilli showed 68, 62, and 65% for trpE, trpD and 5’trpC genes, respectively. Charge related residues …

Amino Acids And N-Acetyl-Aspartyl-Glutamate As Neurotransmitter Candidates In The Monkey Retinogeniculate Pathways, Ricardo A. Molinar-Rode

Dissertations, Theses, and Capstone Projects

The lateral geniculate nucleus (LGNd) receives chemically identified inputs from brain stem structures, the thalamus and visual cortex. The identity of the neurotransmitter(s) in the retinal input, however, is unknown.

To investigate the possibility that some amino acids and certain dipeptides, such as N-acetyl-aspartyl-glutamate (NAAG), fulfill this function, changes in their concentration were measured in the optic tract, parvocellular and magno-cellular segments of the LGNd, superior colliculus and visual cortex of six monkeys (Macaca fascicularis), seven days after right optic tractotomy. The LGNd was studied also in two additional macaques, three months after occipital lobectomy. Tissue was frozen within five …

Aspects Of Mitochondrial Oxidative Metabolism, Leslie Kushner

Dissertations, Theses, and Capstone Projects

The effects of metabolic intermediates and coenzymes on the activities of fatty acyl-CoA synthetase and carnitine palmitoyltransferase (CPT) in rat heart mitochondria were studied. ADP and palmitoyl-l-carnitine were weak inhibitors of fatty acyl-CoA synthetase. CPT A was inhibited 59.3% by 100 (mu)M succinyl-CoA. However, succinate thiokinase activity in rat heart cytosol was too low to maintain a succinyl-CoA concentration sufficient to affect the activity of CPT A. There was no indication that fatty acid oxidation in rat heart mitochondria is controlled via the regulation of either CPT A or fatty acyl-CoA synthetase.

The dependence of the oxidation of unsaturated fatty …
