Molecule: Dna (5'-D(Tpaptpcpgpaptpa)-3') Chain: R, S Engineered: Yes Other_details: 50% Occupancy In The Outermost Positions |
Synthetic: Yes | ||||||||||||||
Molecule: Protein (Cro Repressor) Chain: A Engineered: Yes Mutation: Yes Other_details: Wildtype Cro Does Not Form Stable Monomers. Engineered-Monomer Presented Here Contains A 5-Residue Inse [Dgevk] Following K 56. The First 2 Residues Of This Insert The Formation Of A Beta-Turn. The Remaining 3 Residues Mimi Of The Wildtype Dimer Interface, Allowing Stabilizing Inter Be Maintained. The Overall Structure Of This Monomer Is Qui To A Subunit Of The Wildtype Dimer. |
