C-DES Mutant K223A with GLY Covalenty Linked to the PLP-cofactor
1. Protein Identity and Related Structures Protein Identity & Related Structures
No usable UniProt protein identity is available for this entry.
The relationship tables retain this entry's assembly and composition data, but cross-PDB links for the same protein cannot be established reliably without a unified protein identity.
Assembly Composition of the Current Entry
| Assembly | Physical composition | Protein state | 蛋白 / DNA / RNA / 其他Polymer | Data consistency |
|---|---|---|---|---|
| 1 | Protein homooligomer | Homooligomer | 2 / 0 / 0 / 0 | Consistent with protein count |
The page prioritizes protein identity, the current assembly, associated components, oligomeric state and cross-PDB links. Chain mapping and sequence ranges are retained as data evidence. Internal IDs, import timestamps and assembly operation expressions are maintenance fields and are not shown here.
