HORNET
HydROgen bond NETwork


Interactive WWW TOOL for easy graphics viewing of PDB structures with emphasis on bi-directional coupling of sequence and 3D information. Special attention is given to MacroMolecular INTERFACE analysis.

HORNET Specifically shows Hydrogen Bond Network formed between two protein chains (or protein and DNA). HORNET also shows exact listings of IFR, based on calculated buried surphace are.
