Resumen:
S-layer is a crystalline bidimensional array of proteic or glycoproteic subunits that represents the outermost layer of several species of archea and bacteria.Several specific functions have been assigned to the S-layer from different microorganisms (protective coats, molecular sieves, molecule and ion traps, cell adhesion and surface recognition, virulence factors). Its potential functions have converted S-layer in an attractive target for biophysical studies and structural research, particularly regarding their possible nanotechnological applications [1]. Specifically, the capacity of the S-layer to bind metal ions has attracted the attention due to the potential biotechnological application in biorremediation and nanoelectronics. In spite of these evidences, the information regarding the molecular basis of the S-layer/metal interaction and its consequences on the S-layer secondary structure is still very scarce. For this reason, this work deals with the structural characterization of the interaction S-layer-heavy metals.
