PlantCyc is a metabolic pathway reference database containing more than 1000 pathways and their catalytic enzymes and genes, as well as compounds from over 350 plant species (See Database Statistics).
- The majority of the pathways have been curated from experimental literature by curators at the PMN and collaborators' sites. In addition, PlantCyc includes hypothetical pathways that are published in peer-reviewed journals based on the educated conjectures of experts, and computationally predicted pathways that have been manually validated by PMN curators.
- Similarly, enzymes in PlantCyc may have experimental support or may be based solely on computational predictions.
- For both pathways and enzymes, evidence codes are assigned to clearly indicate the type of support associated with these database items.
