2.7.4.2 | Mg2+ | ligand binding reverses the side-chain orientations of two antiparallel lysines residues 100 and 101 with the result that Lys101 is switched into a position in which its ammonium ion is in direct contact with the beta,gamma-bridging atom of the nucleotide, where it is expected to stabilize both the ground and transition states of the reaction | Streptococcus pneumoniae |

2.7.4.2 | ATP + (R)-5-phosphomevalonate | active site structure and substrate binding coformation, detailed overview. Ligand binding reverses the side-chain orientations of two antiparallel lysines residues 100 and 101 with the result that Lys101 is switched into a position in which its ammonium ion is in direct contact with the beta,gamma-bridging atom of the nucleotide, where it is expected to stabilize both the ground and transition states of the reaction. The active site of PMK seems spacious enough to accommodate interconversion of the reactive and nonreactive conformers. A substantial fraction of the PMK active site is occupied by an active site water pentamer, which clusters near the charged regions of the substrate | Streptococcus pneumoniae | ADP + (R)-5-diphosphomevalonate | - |
