Title FTIR Μελέτες της μυοσφαιρίνης και της caa3 οξειδοαναγωγάσης απο το Thermus Thermophilus
Creator Papadopoulos, Giorgos
Abstract Aim of the present study was the spectroscopic investigation of myoglobin. Myoglobin is a small globular protein, found in red muscles, whose function is to store and facilitate diffusion of oxygen to the mitochondria. The heme group binds reversibly oxygen as well as other small gaseous ligands such as CO and NO. We have applied FTIR spectroscopy to vibrationally characterize the products of the perturbation of the system after photodissosiation of the ligand from heme iron. FTIR spectroscopy proves to be extremely efficient due to it's high sensitivity and spectral resolution. The experiments were conducted at 253 Κ, near physiological temperatures and the results were compared to previously published studies at cryogenic temperatures. The photolysis laser used was a CW laser at 416 nm. In the second part, the kinetic study of caa3 oxydoreductase from Thermus Thermophilus is presented.
