iPNN is a simple web navigator designed to enable search for pathway from one metabolite to another metabolite. To predict the biosynthetic pathway for given chemicals, you can just enter start and end material and click to run.

iPNN uses various biochemical reaction databases such as EBI Rhea, KEGG LIGAND, Metacyc, BRENDA. All data were integrated in iPNN and you can click each link to collect more information.

iPNN is for synthetic biologists who want to design biosynthetic pathway which produces valuable compounds. iPNN helps to discover novel synthetic pathways from all known biochemical reactions.

iPNN also provides information of genes and proteins related to biochemical reactions in the pathway. Eventually, iPNN aims to provide a platform for design of biocircuit in the integrated way.

At present, iPNN provides physical shortest pathway between two input metabolites. We have been developing a variety of algorithms including alternative pathways, organism-specific pathways, and thermodynamically reasonable pathways, etc.
