Ferritin as an iron transport protein ferritin uptake and iron ultilisation by guinea pig placenta

Lamparelli, Rosario D. V. January 1990 (has links)
A dissertation submitted to the Faculty of Medicine, University of the Witwatersrand, Johannesburg in fulfilment of the Degree of Master of Science in the branch of Medicine / The guinea pig clears circulating tissue ferritin in a manner different from other mammals. Previous work in man and in rats has shown that injected tissue ferritin is removed from the plasma predominantly by the liver; however, in the guinea pig it is cleared predominantly by red cell precursors and furthermore, the ferritin iron is utilised directly for haem synthesis. During pregnancy, the foeto-placental complex also has a high requirement for iron. / IT2018

Single-Molecule Imaging of Conformational Dynamics in a Neurotransmitter Transporter Homolog

Kolster, Rachel Ann January 2016 (has links)
Neurotransmitter:sodium symporter (NSS) proteins, the targets of antidepressants and psychostimulants, clear neurotransmitters from the synaptic cleft in a Na+-coupled transport mechanism. Transport is thought to occur via conformational rearrangements that alternately expose the substrate-binding site to each side of the membrane, but little is known about the mechanism by which ligand binding coordinates motions at the two faces. In this dissertation, single-molecule fluorescence resonance energy transfer (smFRET) techniques are used to image the dynamics of the prokaryotic NSS LeuT with sufficient resolution to describe the conformational states at both the intra- and extracellular faces for the first time. We found that the two sides do not move as a rigid body, contrary to popular models, and that previously undetected intermediate states are associated with transport activity. We also describe how ions and substrates influence conformational dynamics to create a productive transport cycle.
