Influence of cysteine residues on monoamine oxidases catalysis
(University of St Andrews, 2003) - ThesisMonoamine oxidases (MAO), types A and B, are flavin-containing enzymes important in the regulation of biogenic amines, including the neurotransmitters, serotonin and dopamine. Cysteine modification inactivates MAO and ... -
The biochemical genetics of sulphate assimilation in barley (Hordeum vulgare)
(University of St Andrews, 1995) - ThesisThe sulphate assimilation pathway was investigated in barley (Hordeum vulgare). The enzymes ATP sulphurylase, thiosulphate reductase, sulphite reductase, serine acetyltransferase and cysteine synthase proposed as steps in ... -
The effects of foliar damage on flower characteristics and pollinator visits in Vicia faba
(University of St Andrews, 2002) - ThesisThis thesis addresses aspects of the interaction of plant herbivory and plant pollination. The experiments examine the effects of leaf damage on the flower characteristics of broad beans (Vicia faba) and resultant changes ... -
Reproductive investment in the zebra finch, Taeniopygia guttata
(University of St Andrews, 2003) - ThesisReproduction is costly; therefore females are predicted to allocate resources depending upon the perceived costs and benefits of a particular breeding attempt. Within a clutch, females are also predicted to invest in ... -
Functions of different neurotrophic factors in regulating neuronal survival in the developing peripheral nervous system
(University of St Andrews, 2000) - ThesisThe main aim of this thesis was to clarify the significance of the GDNF family of neurotrophic factors in neural development. The ability of GDNF, neurturin, persephin and artemin to promote the survival of embryonic chicken ...
