LITERATURE
hanging-drop vapour diffusion method
-
crystal structure exhibits a classic thioredoxin-glutaredoxin fold comprising three alpha-helices surrounding four antiparallel beta-sheets. The crystal lattice has four monomers in a dimer of dimers arrangement. A cadmium ion is found within the active site of each monomer, and two cadmium ions stabilize the N-terminal tails and dimer interfaces. CoMSH and glutathione bind to the active site of methanoredoxin similar to the binding of glutathione in glutaredoxin

sitting-drop vapor diffusion method, crystals belong to the hexagonal space group P6522 with cell dimensions of a = b = 110.3 and c = 68.5 and with one molecule in the asymmtric unit. The structure is solved by multiple isomorphous replacement including anomalous scattering data. The structure is refined to 1.9 resolution
