Protein Details

Name	Description
Molecular Weight	Molecular weight of the protein
Purity (%)	Estimated percentage purity of the sample (e.g., from SDS-PAGE or gel filtration)
Uniport ID	Accession ID linking the protein to the UniProt database.
Number of subunits	How many subunits
AA Sequence	Exact sequence of construct in the NMR tube (including any uncleaved tags or additional amino acids)
Protein conformational state	Specify if the protein is globular, membrane, fibril or disordered
Monomer/Homo-Oligomer	Indicate if the protein exists as a monomer or homo-oligomer; if oligomeric, specify whether it is symmetric or asymmetric.
