Abstract:
Bacterioferritin, an iron storage protein having a 24-subunit quaternary structure, was used as a model for the study of host-guest interactions and guest encapsulation, making use of its spherical cage-like structure. A hexahistidine-affinity tag fused to the C-terminus of each bacterioferritin subunit was constructed. The C-terminus of each subunit points toward the inside of the cavity, while the N-terminus is exposed on the surface of the protein. The hexaHistag was able to form strong interactions with a nickel-nitrilotriacetic acid linked dye molecule (guest) and this interactio

Abstract:
Since its discovery in the early 1940s the element plutonium has been seen by mankind as both an opportunity and a threat. As a radioactive nuclide plutonium presents health hazards in its handling and if mankind is to make the most of this element's potential benefits it is essential that these hazards be understood. Both overestimation and underestimation of these hazards are damaging to its proper utilisation. Many studies have been carried out to determine the effects of plutonium exposure and a broad picture of the biological behaviour of plutonium has been built up. Radiological protecti

This thesis examines the chemistry and biochemistry of hydroxyrnethylpyrroles of the type 1.9 (X = OH). Pyrrolic compounds play an important role in many areas of chemistry and biology. A large number of biomolecules which are essential for life are derived from simple pyrrole precursors, eg porphyrins and haemoglobin. In addition, pyrroles have been utilised as building blocks and key intermediates in synthesis.

Abstract:
Peptidases regulate important physiological processes by controlling levels of bioactive peptides and occasionally through noncatalytic processes. This thesis presents a study of prolyl endopeptidase-like (PREPL), which is a peptidase involved in several human deletion syndromes, including hypotonia-cystinuria syndrome (HCS). Phenotypes tentatively attributed to PREPL deletion include hypotonia and decreased growth hormone (GH) levels. However, little is known about the mechanisms by which PREPL deletion causes these phenotypes. To better understand PREPL catalytic activity, we used an activit

Abstract:
Aromatase is the last enzyme in estrogenesis, and as such is of central importance in estrogen metabolic and reproductive processes. Four central postulates of aromatase active site topology were elaborated: 1. The C-19 cavity postulate predicted that a cavity exists in aromatase. Steroids synthesized to investigate this postulate have confirmed that a 6A deep pocket exists to accommodate C-19 androgen derivatives. 2. The C-3 chelation postulate suggested that chelating groups at the C-3 position might constitute a new generation of aromatase inhibitors and cause aromatase inactivation. Steroi

Deterioration of flavour quality during processing and storage is often brought about by oxidative processes. These typically involve oxygen or an active form of oxygen in effecting transformation of a wide range of volatile and non-volatile compounds, including key quality chemicals, flavour precursors and antioxidants. To investigate the nature of the chemical and biochemical change within vegetables and herbs, unblanched frozen parsley was selected as a suitable tissue.
