  1. Genes: counts are based on the internal database identifiers and include genes encoding for a component of a protein complex as separate entities. EC numbers: including incomplete EC numbers. Reactions: if reactions only differ in direction and/or compartments they are counted as one. Pathways: counts for HumanCyc and Reactome are based on the lowest level of their pathway hierarchy.
