Popis: The crystal structures of a subunit of the formylglycinamide ribonucleotide amidotransferase, PurS, fromThermus thermophilus,Sulfolobus tokodaiiandMethanocaldococcus jannaschiiwere determined and their structural characteristics were analyzed. For PurS fromT. thermophilus, two structures were determined using two crystals that were grown in different conditions. The four structures in the dimeric form were almost identical to one another despite their relatively low sequence identities. This is also true for all PurS structures determined to date. A few residues were conserved among PurSs and these are located at the interaction site with PurL and PurQ, the other subunits of the formylglycinamide ribonucleotide amidotransferase. Molecular-dynamics simulations of the PurS dimer as well as a model of the complex of the PurS dimer, PurL and PurQ suggest that PurS plays some role in the catalysis of the enzyme by its bending motion.
