Crystal structures of 5-aminoimidazole ribonucleotide (AIR) synthetase, also known as PurM, from Thermus thermophilus (Tt) and Geobacillus kaustophilus (Gk) were determined. For TtPurM, the maximum resolution was 2.2 A and the space group was P21212 with four dimers in an asymmetric unit. For GkPurM, the maximum resolution was 2.2 A and the space group was P21212 with one monomer in asymmetric unit. The biological unit is dimer for both TtPurM and GkPurM and the dimer structures were similar to previously determined structures of PurM in general. For TtPurM, approximately 50 residues at the amino terminal were disordered in the crystal structure whereas, for GkPurM, the corresponding region covered the ATP-binding site forming an alpha helix in part, suggesting that the N-terminal region of PurM changes its conformation upon binding of ligands. FGAM binding site was predicted by the docking simulation followed by the MD simulation based on the SO4 2- binding site found in the crystal structure of TtPurM. | |||

FunctionEvolutionary Conservation Check, as determined by ConSurfDB. You may read the explanation of the method and the full data available from ConSurf. Publication Abstract from PubMedCrystal structures of 5-aminoimidazole ribonucleotide (AIR) synthetase, also known as PurM, from Thermus thermophilus (Tt) and Geobacillus kaustophilus (Gk) were determined. For TtPurM, the maximum resolution was 2.2 A and the space group was P21212 with four dimers in an asymmetric unit. For GkPurM, the maximum resolution was 2.2 A and the space group was P21212 with one monomer in asymmetric unit. The biological unit is dimer for both TtPurM and GkPurM and the dimer structures were similar to previously determined structures of PurM in general.
