How does the Volume, internal pH, membrane potential and intracellular cation content change in a time dependent scale during potassium limitation.
Assays: External Potassium Concentration, External pH changes, How does internal potassium change (/decrease) during several hours of p..., How starvation affect protein content in yeast cells, Membrane Potential, Protein Concentration, Time courses of the internal pH changes, Volume determination during starvation at different times.
The enzymes involved in the trypanothione metabolism will be studied in a uniform assay medium that mimics the intracellular milieu of the parasite.

The enzyme Trypanothione Synthetase (TryS) is a complex enzyme that catalyses the two step reaction that forms trypanothione from 2 molecules of GSH and 1 molecule of Spd and the use of ATP

At external potassium concentrations in the range of 10uM to 1mM Trk is major cellular uptake system for potassium. This system responds to the activiy of the proton pump. Transmembrane fluxes of protons and potassium cations are analysed in a signal-response relationship.
The Lactate dehydrogenases (LDH) are key metabolic enzymes in lactic acid bacteria (LAB). The LDH ( E.C. 126.96.36.199) catalyzes the reaction of pyruvate and NADH into lactate and NAD+.We have carried out an experimental and computational study of the effects of fructose-1,6-bisphosphate (FBP), phosphate (Pi) and ionic strength (NaCl concentration) on 3 LDHs from 3 LABs studied at pH 6 and pH 7.
