B4DIMER: A DE NOVO DESIGNED EIGHT-STRANDED BETA-SHEET ASSEMBLED USING A DISULFIDE BOND
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.
