CRYSTAL STRUCTURE OF AZURIN II AT ATOMIC RESOLUTION (1.13 ANGSTROM)
Overview
Understanding how the active site structures of blue copper proteins, determine their redox properties is the central structure-function, relationship question of this important class of protein, also referred to, as cupredoxins. We here describe both experimental and computational, studies of azurin, plastocyanin and stellacyanin designed to define more, accurately the geometric structures of the active site of the reduced and, oxidized species, and thus to understand how these structures determine, the redox potentials of these proteins. To this end the crystal structure, of reduced azurin II has been determined at an atomic resolution of 1.13, Angstrom and is presented here. Co-ordinates and structure factors have, been deposited in the RCSB Protein Data Bank with accession codes 2ccw ... [(full description)]
