Reading this structure
This is an experimentally determined structure, not a predicted model. A co-crystallised ligand, if any, does not by itself show binding affinity. The structure says nothing about kinetics, pathway rate or metabolic flux.
Snapshot provenance
Each row is a source snapshot this record was built from: when it was retrieved, its path and SHA-256 digest, and the exact request. The snapshot files stay with the build and are not served here. These rows document this record; they are not general citations.
