The molecular biology of calbindin-D₉
Calbindin-D9k is a cytosolic calcium binding protein expressed in the mammalian intestine, placenta, and uterus. The protein is probably involved in calcium transport across the intestinal and placental epithelia. The objective of this thesis was to study the structure of the human and porcine …

Molecular biology and biochemistry of brain tumours
ßElucidating some molecular mechanisms and biochemistry of brain tumours is an important step towards the development of adjuvant medical therapies. The present study concentrates on cholecystokinin (CCK), a gut-brain peptide that has been described to be able to induce mitosis of rat gliomas as …

The Molecular Biology of Lichen Symbiosis and Development
… two very different organisms. Identifying the molecular basis of microbe recognition and interactions remains one of the greatest challenges in studying symbiotic systems. </p><p>In this thesis, I determine the stage in which to begin looking for lichen symbiosis specific genes, and then …

Experimental investigations of mastrevirus molecular biology and evolution
This dissertation describes three major sets of experiments, all of which involved the construction and use of various reciprocal chimaeric MSV constructs. First, chimaeric viruses were used in genetic complementation-type experiments to investigate the biological significance of interactions …

MOLECULAR BIOLOGY OF HEPATITIS B VIRUS DNA-CELL INTERACTION
Liver-specificity of hepatitis B virus (HBV) replication has been attributed to the action of its second enhancer (EII). This thesis reports the characterization of EII and the subsequent isolation of a novel liver-specific DNA-binding protein which binds to, and activates EII. The cDNA clone of …

Molecular biology studies on thecyd operon of Escherichia coli
The Cytochrome d terminal oxidase complex is one of two terminal oxidases in the aerobic respiratory chain of Escherichia coli. The enzyme is located in the cytoplasmic membrane where it oxidizes ubiquinol-8 and reduce oxygen to water. The enzyme is an $\alpha\beta$ hetero-dimer containing hemes …

Molecular Biology of Desiccation Tolerance in the Cyanobacterium Nostoc commune
The molecular biology of desiccation tolerance was investigated in the cyanobacteria with emphasis on Nostoc commune. Analysis of DNA from 41 samples of desiccated Nostoc spp. of varied age and global distribution led to the amplification of 43 independent tRNALEU(UAA) group 1 intron sequences. …

Scale-Free Networks in Molecular Biology: Algorithms and Random Walks Analyses
… of algorithms for scale-free networks in molecular biology and II) the analysis of biological networks using random walks and related algorithms. I: Many systems in nature and society are described by means of complex networks. Research indicates that these complex networks exhibit …

Biochemistry and molecular biology of binding proteins for plant growth regulators.
Plant growth regulators have a vital role in plant growth and development. The cellular response to these regulators depends on the presence and the action of specific receptors. The plant growth regulators and their receptors act together in complexes which determine the final effects of the plant …

Molecular biology of segment 8 of the influenza A virus genome
… presents investigations into two aspects of the biology of the smallest (8th) segment: 1) a possible new gene product and 2) interactions of the viral non-structural protein translated from this segment – NS1 – with a host cell protein during infection. 1) The genome of influenza A virus is …

Systems analysis of Crassulacean acid metabolism (CAM) physiology and molecular biology
… the regulatory landscape of CAM using systems biology approaches. The scope of the regulatory landscape was drawn around the mesophyll metabolism of the dicotyledonous obligate CAM genus, *Kalanchoe*, even though the computational frameworks that had been developed here can also be applied to …

Molecular biology studies on the extracellular serine proteases of Vibrio alginolyticus
Vibrio alginolyticus is a gram-negative aerobic bacterium that produces several extracellular serine proteases and a collagenase during the stationary growth phase. The aim of this study was to investigate alkaline serine protease production by this organism, and to attempt the cloning and …

Integrating Concepts in Modern Molecular Biology into a High School Biology Curriculum
… any other science in the past several decades, Biology has seen an explosion of new information and monumental discoveries that have had a profound impact on much more than the science itself. Much of this has occurred at the molecular level. Many of these modern concepts, ideas, and …

The biochemistry and molecular biology of intercellular adhesion in plant tissue culture
The adhesion between neighbouring plant cells is established as cells are formed during cytokinesis through the middle lamella that is made principally of pectins and proteins. Pectins are secreted into the cell wall in a highly methylesterified form and subsequently de-esterified in muro by pectin …

Structure and Molecular Biology of the Pyruvate Dehydrogenase Complex from Bacillus stearothermophilus
The pyruvate dehydrogenase multienzyme complex (PDHC) from the thennophilic, Gram-positive bacterium Bacillus stearothermophilus is assembled around a core of 60 copies of the dihydrolipoamide acetyltransferase (E2p) component, organized with icosahedral symmetry. The peripheral subunits, attached …
