G-quadruplex (G4 DNA)

Update: 29/08/2024

Among the G4 DNA structures registered in the PDB (38 X-Ray structures), 12 structures selected to avoid sequence duplication are listed here. For each G4 DNA, a 2D map was created using RNApdbee 2.0. These 3D structures can be observed using Molmil viewer. At present, only X-Ray structures are listed here, but NMR structures will be added in the near future.
