Mechanistic studies on enzymes of secondary metabolism : 5'-fluoro-5'-deoxyadenosine synthase and 1-deoxy-D-xylulose-5-phosphate reductoisomerase
(University of St Andrews, 2006) - ThesisA fluorination enzyme (fluorinase) has recently been isolated in St. Andrews from the bacterium Streptomyces cattleya. This enzyme mediates a reaction between fluoride ion and Sadenosyl-L-methionine (SAM) to generate ... -
Studies of excitotoxicity in cerebellar granule neurons
(University of St Andrews, 2004) - ThesisExcitotoxicity is defined as neuronal cell death caused by hyperactivation of ionotropic glutamate receptors (namely NMDA-, AMPA- and KA-receptors). The excitotoxic potential of a novel AMPA receptor subtype-selective ... -
Mechanisms of G2 chromosomal radiosensitivity of murine SCID cells
(University of St Andrews, 2001) - ThesisThe non-homologous end-joining (NHEJ) pathway of DNA repair has become a recent focus of attention and one of the central players of this pathway is DNA-PKCs which is mutated in murine Severe Combined Immunodeficiency ... -
The effects of insect visitation on floral colour change
(University of St Andrews, 2003) - ThesisThis study investigated the effects of flower visitation on floral colour change and the subsequent influence of such change on insect foraging behaviour. Colour change was examined in six plant species; Myosotis sylvatica, ... -
Development of foraging in wild chimpanzees
(University of St Andrews, 2000) - ThesisRecent work on social learning in primates has primarily been approached from a perspective that focuses on demonstrating human-like learning abilities rather than the efficacy of social learning within natural and ...
