PDB entries containing POMs which are not modeled in the protein structure.
PDB entry | Protein (organism) | Number of metal atoms | Origin of POM | Purpose of POM use | POM impact on crystallization/structure | Ref. |
---|---|---|---|---|---|---|
4PE5 | NMDA receptor ion channel (R. norvegicus) | 12 W probably [H2W12O40]6− | Soaking in Na6[H2W12O40] | Heavy atom derivative for phasing. | Improvement of crystal quality | [99] |
3FYH | DNA repair and recombination protein RadA (M. voltae) | 12 W probably [H2W12O40]6− | Added as Na6[H2W12O40] | Rad inhibitor | Stabilization of the inactive form | [100] |
2G8H | RNase H (B. halodurans) | 6 V maybe Lindqvist [V6O19]8− | Self-assembly in the presence of NaVO3 | VO3− as substrate mimic | Stabilization of an intermediate conformation | [101] |
