1	Protein monomer Monomer Protein × 1 PDB declaration: monomeric（1） Consistent with protein copy count	Chain A； UniProt 1–63	Not recorded	ZN ZINC ION × 2	SOLUTION NMR mmCIF provides none of the parsed experimental conditions	Resolution not provided

Other States of the Same Protein in the Database

Each row is a biological assembly of the same UniProt protein in another PDB entry. The “Difference from current entry” column identifies evidence-level differences; no tag means the currently parsed fields agree.

No other PDB entry for the same UniProt protein was found.
