Research Area Glutathione and Sulphur Metabolism in Yeasts |
Research Focus Our current interests are related to different aspects of glutathione and sulphur metabolism in yeasts. Glutathione, γ-glutamyl cysteinyl glycine, an unusual thiol containing tripeptide that is present in high concentrations in almost all eukaryotic cells, plays multiple roles including protection from oxidative stress, maintenance of the cellular redox buffer, in mitochondrial iron-sulphur metabolism, in gene regulation, and in metal and drug detoxification. Glutathione metabolism is intimately linked to sulphur metabolism owing to the presence of the key cysteine residue, and we thus also investigate aspects of sulphur metabolism related to glutathione homeostasis. Our principal focus is on understanding how glutathione levels are maintained in the cell, and we are examining different pathways that contribute towards this maintenance. This includes the high affinity plasma membrane transporter of glutathione that was identified in our lab, the classical and two recently discovered non-classical pathways of glutathione degradation (also discovered in our lab) biosynthesis, organellar compartmentalization and utilization of glutathione. We are attempting to not only understand these different pathways and their regulation in detail, but are interested in integrating these pathways and their regulation into a larger picture of glutathione homeostasis in living cells. |
