This event has been computationally inferred from an event that has been demonstrated in another species.
The inference is based on the homology mappings from Ensembl Compara. Briefly, reactions for which all involved PhysicalEntities (in input, output and catalyst) have a mapped orthologue/paralogue (for complexes at least 1% of components must have a mapping) are inferred to the other species. High level events are also inferred for these events to allow for easier navigation.
