* =
The numbers denote the enzyme-organism-(protein-)commentary-reference-specific occurrences. For kinetic values (Km, Ki, kcat) and ligand-specific fields (Inhibitors, Activating Compounds, Ligands) the corresponding enzyme ligand is also taken into account.
For example, when the identical pI (isoelectric point) was measured for different enzymes or the identical enzyme from different organisms the information is included for each EC number and organism-specific enzyme isoform, respectively.
