Route finder

Choose a starting molecule. Every recorded reaction is walked — forwards through irreversible steps, both ways through reversible ones — and everything reachable is listed. Pick a destination for the full route with the enzyme on each hop.

Carriers

Clear

Carriers are excluded by default. ATP and NAD+ take part in most reactions, so including them makes everything reachable from everything and the answer stops meaning anything.

Reachable from GDP

Distance is the shortest recorded chain of enzymatic steps, not a claim about flux.

Nothing reachable within 6 hops

This is a common carrier, excluded from traversal by default. Switch carriers to Include, or start from a pathway metabolite.
