Complexes

Multi-protein assemblies

Many PDB files contain complexes in which a biological molecule is interacting with another biological molecule in a complex or assembly. These interactions, if biologically relevant, can be immensely insightful in shedding light on cellular and extracellular processes.

ExamplesExamples

• Ribosome
• T7 RNA Polymerase
• Mouse Toll-like receptor bound to dsRNA
• Human Follicle-Stimulating Hormone Complexed with its Receptor
• Platelet-receptor glycoprotein Ib alpha bound to the von Willebrand Factor A1 Domain
• Plant Viral Protein p19 Suppression of RNA Silencing
• RecG Bound to Three-Way DNA Junction
