Structure of a Nudix Protein from Pyrobaculum aerophilum Solved by the Single Wavelength Anomolous Scattering Method
Overview
Nudix proteins, formerly called MutT homolog proteins, are a large family of proteins that play an important role in reducing the accumulation of potentially toxic compounds inside the cell. They hydrolyze a wide variety of substrates that are mainly composed of a nucleoside diphosphate linked to some other moiety X and thus are called Nudix hydrolases. Here, the crystal structure of a Nudix hydrolase from the hyperthermophilic archaeon Pyrobaculum aerophilum is reported. The structure was determined by the single-wavelength anomalous scattering method with data collected at the peak anomalous wavelength of an iridium-derivatized crystal. It reveals an extensive dimer interface, with each subunit contributing two strands to the beta-sheet of the other subunit. Individual subunits consist of a mixed highly twisted and curved beta-sheet of 11 beta-strands and two alpha-helices, forming an alpha-beta-alpha sandwich. The conserved Nudix box signature motif, which contains the essential catalytic residues, is located at the first alpha-helix and the beta-strand and loop preceding it. The unusually short connections between secondary-structural elements, together with the dimer form of the structure, are likely to contribute to the thermostability of the P. aerophilum Nudix protein.
