What do the nodes/entity and edges represent in a pathway/network?
Nodes: The nodes in a pathway/network are mostly representative of proteins, enzymes, families of proteins/enzymes, biological processes, functions, complexes or small molecules. Edges: The edges in a pathway/network represent the molecular interaction between two molecules. The type of interaction can be binding, expression, metabolism, promoter binding, protein modification, regulation or transport. Note: Edge length does not mean any thing in a PathwayWorld network.
